This add-on generates a flyout sidebar which can help with mobile support.

FacetWP Flyout menu add-on

By default, the flyout shows all facets that are on the page itself (except Pager facets, Map facets and User Selections), in the same order as they are on the page, including multiple instances of the same facet.

If you want to limit the facets shown in the flyout, or change their order, see the example below. User Selections (and other content or extra elements) can be added to the flyout by adding them to the flyout’s template, as demonstrated in the example below.

Usage

First, download and install the add-on plugin, and activate it.

Then, add a button or link with the CSS class facetwp-flyout-open to trigger the flyout:

Button example:

<button class="facetwp-flyout-open">Show filters</button>

Link example:

<a href="javascript:;" class="facetwp-flyout-open">Show filters</a>

Translate the button text

If you need to translate the button text, you’ll have to add the button with PHP:

How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
 echo '<button class="facetwp-flyout-open">'. facetwp_i18n( __( 'Show filters', 'fwp-front' ) ) . '</button>';

This makes the button text a translatable string that will appear in e.g. WPML string translations or any other translation plugin. The string can also be translated with WP’s gettext filter (see this example). The button text can now also be translated with the facetwp_i18n hook.

If you want to hide the button/link for desktop users, add the following into your style.css. This hides the flyout button/link on window/device widths above 779px (adjust the width as needed):

How to use custom CSS?
CSS code can be placed in your (child) theme's style.css file. Alternatively, you can add it manually between <style> tags in the <head> section, in your (child) theme's header.php file. You can also load it with a hook in your (child) theme's functions.php file, or in the Custom Hooks add-on. To load the code only on pages with facets, use the facetwp_scripts hook. To load it on all pages, use wp_head or wp_footer.  Or you can use a code snippets plugin. More info
@media (min-width: 780px) {
  .facetwp-flyout-open {
    display: none;
  }
}

Add a flyout button with an Elementor FacetWP Button widget

Add a flyout button with an Elementor add-on FacetWP Button widget.

If you are using Elementor, with the Elementor add-on installed, you can use the FacetWP Button widget to place a flyout button on your page.

Just add the FacetWP Button widget, and select “Flyout button” as the button type.

Facet headings / labels

The Mobile Flyout automatically adds each facet’s label as <h3> heading above it.

If you want to change the HTML of these headings, for example change the <h3> to <h2>, see the example below.

To translate these labels/headings you can use the facetwp_i18n hook.

Hide the facet headings / labels

If you want to hide all facet headings in the flyout, add the following into your (child) theme’s style.css:

How to use custom CSS?
CSS code can be placed in your (child) theme's style.css file. Alternatively, you can add it manually between <style> tags in the <head> section, in your (child) theme's header.php file. You can also load it with a hook in your (child) theme's functions.php file, or in the Custom Hooks add-on. To load the code only on pages with facets, use the facetwp_scripts hook. To load it on all pages, use wp_head or wp_footer.  Or you can use a code snippets plugin. More info
.flyout-row h3 {
  display: none;
}

To hide only specific facet headings, you can use the following CSS instead:

/* Replace 'myfacetname' with the name of your facet */
.flyout-row.name-myfacetname h3 {
  display: none;
}

And if you want to hide one or more of these headings in specific situations only, you can use the Conditional Logic add-on with a rule that uses a custom selector.

Remove or change the facet headings / labels

If you want to remove the facet headings from the flyout code entirely, you can use the following code:

How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_action( 'wp_head', function() {
  ?>
  <script>
    (function($) {
      $(function() {
        if ('object' != typeof FWP) return;

        /* Modify each facet's wrapper HTML */
        FWP.hooks.addFilter('facetwp/flyout/facet_html', function(facet_html) {
          return facet_html.replace('<h3>{label}</h3>', ''); // Sets the heading output to an empty string
        });
      });
    })(jQuery);
  </script>
  <?php
}, 100 );

The same snippet can be changed slightly to change the headings’ HTML tag.

JavaScript functions

The following functions are available to open and close the flyout:

How to use custom JavaScript code?
JavaScript code can be placed in your (child) theme's main JavaScript file. Alternatively, you can add it manually between <script> tags in the <head> section of your (child) theme's header.php file. You can also load it with a hook in your (child) theme's functions.php file, or in the Custom Hooks add-on. To load the code only on pages with facets, use the facetwp_scripts hook. To load it on all pages, use wp_head or wp_footer. Or you can use a code snippets plugin. More info
FWP.flyout.open(); // open the flyout
FWP.flyout.close(); // close it

JavaScript hooks

The following hooks are available to customize the flyout’s content and behavior:

Customize the facets and facet order

By default, the flyout shows all facets that are on the page itself (except Pager and Map facets), in the same order.

If you want to limit the facets shown in the flyout, or change their order, you can add the following code to your (child) theme’s functions.php. Just pass the desired (or all) facet names in the array, in the order you want them to appear in the flyout:

PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_action( 'wp_head', function() {
  ?>
    <script>
      (function($) {
        $(function() {
          if ('object' != typeof FWP) return;
          FWP.hooks.addFilter('facetwp/flyout/facets', function(facets) {
            return ['facet_name3', 'facet_name1', 'facet_name2']; /* Choose which facets to display in the flyout, and/or change the facet display order */
          });
        });
      })(jQuery);
    </script>
  <?php
}, 100 );

Alternatively, you can exclude facets from the flyout with the following code:

      (function($) {
        $(function() {
          if ('object' != typeof FWP) return;
          FWP.hooks.addFilter('facetwp/flyout/facets', function(facets) {
            const exclude_flyout = ['facet_name1', 'facet_name2', 'facet_name3']; /* list facets to exclude as array */
            facets = facets.filter(function(el) {
              return exclude_flyout.indexOf(el) < 0;
            });
            return facets;
          });
        });
      })(jQuery);
    </script>
  <?php
}, 100 );

Modify each facet’s HTML

This code example changes the facet label heading tags from <h3> to <h2>:

    <script>
      (function($) {
        $(function() {
          if ('object' != typeof FWP) return;

          /* Modify each facet's wrapper HTML */
          FWP.hooks.addFilter('facetwp/flyout/facet_html', function(facet_html) {
            return facet_html.replace('<h3>{label}</h3>', '<h2>{label}</h2>'); // Example: replace <h3> facet label tags with <h2>
          });
        });
      })(jQuery);
    </script>
  <?php
}, 100 );

Modify the flyout wrapper HTML

This code example replaces the “x” in the close icon to a link with the word “Close”:

      (function($) {
        $(function() {
          if ('object' != typeof FWP) return;

          /* Modify the flyout wrapper HTML */
          FWP.hooks.addFilter('facetwp/flyout/flyout_html', function(flyout_html) {
            return flyout_html.replace(' <div class="facetwp-flyout-close">x</div>', ' <div class="facetwp-flyout-close"><a>Close</a></div>'); // Replace "Close" with your desired text
          });

        });
      })(jQuery);
    </script>
  <?php
}, 100 );

Customize the flyout’s open / close events

With the following hooks, you can customize what happens on opening or closing the flyout:

How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_action( 'wp_head', function() {
  ?>
    <script>
      (function($) {
        $(function() {
          if ('object' != typeof FWP) return;

          /* Flyout opened */
          FWP.hooks.addAction('facetwp/flyout/open', function() {
            // do something
          });

          /* Flyout closed */
          FWP.hooks.addAction('facetwp/flyout/close', function() {
            // do something
          });

        });
      })(jQuery);
    </script>
  <?php
}, 100 );

Adding extra content to the flyout

To add extra flyout content, add an HTML element to the page and give it a facetwp-flyout-tpl class. It will automatically get hidden with CSS.

Within this element, add a {content} placeholder to automatically output the facets. Then add additional content above or below this placeholder. This content can be text, HTML, or shortcode(s).

Here’s a full example:

<div class="facetwp-flyout-tpl">
  This text/HTML/shortcode appears above the facets.
  {content}
  This text/HTML/shortcode appears below the facets.
</div>

Add User Selections to the flyout

You can use shortcodes within the facetwp-flyout-tpl HTML block. For example, if you want to show the User Selections above the other facets in the flyout, place this HTML block somewhere on the page. It will automatically get hidden with CSS:

<div class="facetwp-flyout-tpl">
  [facetwp selections="true"]
  {content}
</div>

Make the facets in the flyout collapsible

If you have many facets in the flyout, you may want to make room by expanding/collapsing the facets in an accordion style.

The example below uses the <h3> headings which are already above each facet, as expand/collapse buttons and toggles an expanded class:

How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_action( 'wp_head', function() {
  ?>
    <script>
      document.addEventListener('DOMContentLoaded', function() {
        fUtil().on('click', '.flyout-row h3', function() {
          fUtil(this).closest('.flyout-row').toggleClass('expanded');
        });
      });
    </script>
<?php });

The above code will not work without the following CSS. It uses the expanded class to show/hide the facets, and adds a [+]/[-] icon to the right of the headings. Instead of using the wp_head hook, you can also add the CSS rules directly to your theme’s style.css:

PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_action( 'wp_head', function() {
  ?>
    <style>
      .flyout-item {
        display: none;
      }

      .flyout-row.expanded .flyout-item {
        display: block;
      }

      .flyout-row h3 {
        cursor: pointer;
      }

      .flyout-row h3:after {
        content: "[+]";
        font-weight: normal;
        font-size: 0.8em;
        float: right;
      }

      .flyout-row.expanded h3:after {
         content: "[-]";
      }
    </style>
<?php } );

Flyout from the right

To make the flyout menu slide in from the right instead of the left, you can use the following CSS. Instead of using the wp_head hook, you can also add the CSS rules directly to your theme’s style.css:

How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_action( 'wp_head', function() {
  ?>
    <style>
      body .facetwp-flyout {
        right: 0;
        transform: translateX(100%);
      }
    </style>
<?php });

Fix duplicate facets in the flyout

If you’re seeing duplicate facets in the Mobile Flyout, and you are using Elementor Pro, make sure not to use the “Sticky” option in any Elementor widgets that contain facets.

Open the flyout on first page load when facets are in use

To open the flyout automatically on first page load when the URL contains facet selections, add the following code to your (child) theme’s functions.php:

How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_action( 'facetwp_scripts', function() { ?>
    <script>
      (function($) {
        document.addEventListener('facetwp-loaded', function() {
          // Check if there are active facets
          const noFacets = Object.values(FWP.facets).every(arr => arr.length === 0);
          // If it is the first page load and there are active facets
          if (!FWP.loaded && !noFacets) {
            // Open the flyout
            FWP.flyout.open();
          }
        });
      })(fUtil);
    </script>
<?php },100 );

This can be useful if your facets are only in the flyout, and hidden on the page. And in combination with a facet URL linked from another page, like the front page, with the Submit Button add-on.

Close the flyout when facets are selected

Below are several solutions to let the flyout close automatically after interaction with one or more facets, without the user having to click the x close button:

Close the flyout when any facet is used

To automatically and immediately close the flyout menu when a user makes any facet selection, you can use the following snippet:

How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_action( 'facetwp_scripts', function() { ?>
  <script>
    (function($) {
      document.addEventListener('facetwp-refresh', function() { // Or use the 'facetwp-loaded' event to close it after the results have finished loading.
        if (FWP.loaded && $('.facetwp-flyout').hasClass('active') ) {
          FWP.flyout.close();
        }
      });
    })(fUtil);
  </script>
<?php } );

The above snippet uses the facetwp-refresh event, which will make the flyout close immediately when any facet choice is clicked. You could also use the facetwp-loaded event, which will make the flyout close a bit later, after the updated results have finished loading.

Close the flyout when a specific facet or facet type is used

To close the flyout when a specific facet is used, you can use the following snippet. Make sure to replace my_facet_name with the name of your facet:

How to use custom PHP code?
PHP code can be added to your (child) theme's functions.php file. Alternatively, you can use the Custom Hooks add-on, or a code snippets plugin. More info
add_action( 'facetwp_scripts', function() {
  ?>
  <script>
    document.addEventListener('facetwp-refresh', function() {
      if (null !== FWP.active_facet) {
        let facet = FWP.active_facet;
        let facet_name = facet.attr('data-name');
        // let facet_type = facet.attr('data-type'); // Or you can use the facet type

        if ( facet_name == "my_facet_name") { // Replace "my_facet_name" with the name of your facet
          FWP.flyout.close();
        }
      }
    });
  </script>
  <?php
} );

If you use facet_type as check instead, you can make the flyout close when using a specific facet type.

Close the flyout when a submit/apply/filter button in the flyout is clicked

If you want the flyout to close only after a user has made one or more facet choices and then clicks a submit/apply/filter button, you can do it as follows:

  1. Disable FacetWP’s auto-refresh feature and add an submit/apply/filter button to your desktop page.
  2. Add an submit/apply/filter button also to the bottom (or top) of your flyout menu, by adapting the template for the flyout content, like this: 
    <div class="facetwp-flyout-tpl">
  {content}
  <button onclick="FWP.refresh()">Apply</button>
</div>

    This HTML needs to be added to your page, as explained above.

  3. Then add the above snippet to let the flyout close when the button is clicked.

Note that your desktop page also needs an apply/submit button, as it is not possible to disable FacetWP’s auto-refresh for the flyout menu only.
