A list of checkboxes, where customers can make multiple choices. It’s best suited for non-visual types of product data where customers need to select more than one option at a time – for example, size, brand, model, etc.
Available options
| Option name | Description |
| Data source | Where should the checkbox items come from? Read more about data sources. |
| When to show | Always – a filter will always be displayed Auto – a filter will be visible conditionally. Read more about content-aware filters. |
| Logical operator | “OR” is the most common logical operator used for checkboxes OR (match any) – products that match any of the selected attribute values will be included. For example, if you select “Pot material” values of Aluminum and Enamel, aluminum and enamel pots will both appear. AND (match all) – products that match all of the selected attributes will be included. For example, if you select “Pot material” as Aluminum, you won’t be able to select “Enamel” because that would mean displaying pots that are both aluminum and enamel – such products don’t exist. The AND operator is useful for features that do not mutually exclude each other, such as car accessories. |
| Values order | In what order should the checkbox features be presented? Alphabetically – sorts choices alphabetically Numerically – sorts choices numerically (only visible when all filter values are numbers) By counters – sorts choices by the total number of products assigned with that feature By term order – determines the sort order of the terms using custom ordering. Custom ordering is supported by WooCommerce, but there are plugins that do this job as well. Currently, we don’t support these plugins. |
| Display the filter name in applied filters | If users select features in the Checkboxes filter, they will also be displayed above the products in a special section called “Applied filters”. With this option enabled, the “Filter name” and “Selected feature” will be displayed as shown in the screenshot below. Inversely, when the option is disabled, only “Selected feature” will be shown.  |
Expanding hierarchical checkboxes
By default, hierarchical checkboxes are expanded to level 0, showing only parent checkboxes. You can modify this with the following code:
add_filter( 'fibofilters/config/expand_to_level', fn() => 1 );

This will show the parent checkboxes and their direct children.
Override expansion level for specific filters
To set a custom expansion level for a specific filter, like the “categories” filter, use this code:
add_filter( 'fibofilters/config/overrides', function () {
return [
'categories' => [
'expand_to_level' => 2,
],
];
} );

This will expand the “categories” filter to level 2:
