Filter: bricks/filter_element/data_source_{filter_source}

Filters the data source (options) for a specific filter source. The {$filter_source} portion of the hook name should be replaced with the actual source name.

Built-in taxonomy, wpField, and customField sources are handled before this dynamic filter runs. Use this hook for custom filter sources that Bricks does not populate internally.

Parameters

• $data_source (array): Array of filter options. Each option should be an associative array with keys like value, text, class, etc.
• $element (object): The filter element instance.

Example usage

// Populate options for a custom source 'my_source'
add_filter( 'bricks/filter_element/data_source_my_source', function( $data_source, $element ) {
    $data_source[] = [
        'value' => 'option_1',
        'text'  => 'Option 1',
    ];

    $data_source[] = [
        'value' => 'option_2',
        'text'  => 'Option 2',
    ];

    return $data_source;
}, 10, 2 );
