X Buy Features Demo (Cars) Demo (Power Plants) Demo (Map) Showcase Add-ons Docs Changelog


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

To see it in action, browse to our Cars demo then shrink your browser width until you see the purple “Show filters” button.


Add a button or link with the CSS class of facetwp-flyout-open to trigger the flyout.

<button class="facetwp-flyout-open">Filter</button>

If you want to hide the button for desktop users, add this into your style.css:

@media (min-width: 780px) {
    .facetwp-flyout-open {
        display: none;

That’s it! Everything below is totally optional.

JS functions

FWP.flyout.open(); // open the flyout
FWP.flyout.close(); // close it

JS hooks

(function($) {

    FWP.hooks.addFilter('facetwp/flyout/facets', function(facets) {
        return ['facet3', 'facet1', 'facet2']; // change the facet display order

    FWP.hooks.addAction('facetwp/flyout/open', function() {
        // flyout opened

    FWP.hooks.addAction('facetwp/flyout/close', function() {
        // flyout closed


Adding extra content

To add extra flyout content, add a .facetwp-flyout-tpl HTML element on the page. 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. Here’s a full example:

<div class="facetwp-flyout-tpl">
  This text appears above the facets!
  This text goes below the facets.



* Added support for custom flyout content (see the “Adding extra content” section in the docs)

* Modified CSS classes to allow for better style targeting
