Product Filter – Search

This section focuses on the search filter feature provided by the Product Filter – Search widget, its equivalent [woocommerce_product_filter] shortcode or the corresponding API function. We will be exploring how to change the look and feel of it, and indistinctively refer to the Product Filter – Search whether generated by the widget or any other means. To clarify, this field should not be confused with the live search field for which we provide guidance on customization under Product Search Field. Here is an example of HTML generated typically for this field:

<div id="product-filter-search-0" class="product-search product-filter product-search-filter-search">
    <div class="product-search-form">
        <form id="product-filter-search-form-0" class="product-search-form " action="http://example.com/shop/" method="get">
            <input id="product-filter-field-0" name="ixwpss" type="text" class="product-filter-field" placeholder="Search" autocomplete="off" value="">
            <input type="hidden" name="title" value="1">
            <input type="hidden" name="excerpt" value="1">
            <input type="hidden" name="content" value="1">
            <input type="hidden" name="categories" value="1">
            <input type="hidden" name="attributes" value="1">
            <input type="hidden" name="tags" value="1">
            <input type="hidden" name="sku" value="1">
            <noscript><button type="submit">Search</button></noscript>
            <span class="product-search-filter-search-clear" style="display:none">Clear</span>
    <div id="product-filter-results-0" class="product-filter-results"></div>
Please note that the element IDs might be slightly different on your setup and dependent on the page configuration and templates. For most cases tough, the IDs used above should concur with those on your site. In what follows, we have prepared examples that are aimed at helping you master the style customizations for the Product Search – Filter.
  • Styling the Field
  • Changing the Loader Icon
To place us into context, here is the Product Filter – Search field within the context of our demo shop:  

Styling the Field

↑ Back to top
In this example we are adding a colored search icon inside the search field, we will apply a bright border to it and we will also change the appearance of the field’s text. To make it easier to understand, let’s change the appearance first and we will add the search icon in a second step. This is the field’s appearance before we apply our customizations: These are the CSS rules we apply:
#product-filter-field-0 {
    border: solid 4px #cc33ff;
    border-radius: 8px;
    background-color: #fff;
    color: #3366aa;
    font-size: 18px;
    font-weight: bold;
    padding: 8px 8px 8px 28px;
    outline: none;
With the above rule applied, the field now looks like this: Now, with a second CSS rule we will add a search icon. Note that we are using an icon from the font Font Awesome 5 Free which is included with the extension’s resources.
#product-filter-search-form-0::before {
    display: inline-block;
    font-style: normal;
    font-variant: normal;
    font-weight: normal;
    line-height: 1;
    font-family: 'Font Awesome 5 Free';
    font-weight: 900;
    vertical-align: baseline;
    content: "\f002";
    position: absolute;
    top: 1.3em;
    left: 1em;
    color: #33bb33;
With this second rule added, our field now also shows a search icon: Let’s have a look at it within the context of our demo store … Yeah, pretty bright! And it was really easy, too! Remember that you can add your customized CSS rules to your child theme’s stylesheet or use the inline stylesheet feature provided by the extension.  

Changing the Loader Icon

↑ Back to top
Next up is our example of how you can change the animated icon that is displayed while something’s going on behind the scenes, i.e. when the search engine is pulling in updated results to be displayed on the shop page. You can use an icon of your own choice by changing the background image of the Product Filter – Search input field when it has the .blinker class. So here’s an example of what we want it to look like … To achieve that, we simply add the following CSS rule to our child theme’s stylesheet:
.product-search-form input.blinker {
    background-image: url( 'custom-loader-icon.gif' );
    background-position: right 8px center;
    background-repeat: no-repeat;
    background-size: 24px;
Here is an example of our chosen new loader icon shown on the field within the context of our demo shop.

Child Themes vs. Inline Stylesheet

↑ Back to top
We recommend to use a child theme with an appropriate stylesheet to implement the CSS rules. The section Set up and use a child theme in the documentation can help you get started with that Alternatively, the extension also provides a handy way of including those customizations using an inline stylesheet feature, see the CSS section for details.
