// How to Customize the Facet Loader

By default, loading images will appear whenever facets refresh. However, this can be totally customized in FacetWP 1.6.0 and above.

Change the loader image

When facets refresh, the facet options get replaced with a loading <div>:

<div class="facetwp-loading"></div>

It uses a CSS background image, which can be changed with a little extra CSS:

.facetwp-loading {
    background: url(PATH_TO_YOUR_IMAGE.png) no-repeat;
}

Add entirely custom actions

FacetWP 1.6.0 includes a way to add a custom loading handler. It involves attaching a function to the FWP.loading_handler javascript variable.

<script>
(function($) {
    $(function() {
        // Make checkbox options semi-transparent
        FWP.loading_handler = function(params) {
            params.element.find('.facetwp-checkbox').css('opacity', 0.5);
        }
    });
})(jQuery);
</script>

When using FWP.loading_handler, an object with 3 elements is passed in:

params.element    // the facet DOM element
params.facet_name // the facet name
params.facet_type // the facet type

Hide the loading animation

To skip the loading animation, set FWP.loading_handler to an empty function:

<script>
(function($) {
    $(function() {
        FWP.loading_handler = function() { }
    });
})(jQuery);
</script>
