Parameters

Parameter	Type	Description
rawAction	string	The filter option toggle ID (e.g. `"pf_st_color-toggle"`)
option	any	Filter option configuration containing a `values` array

Returns:

void

Example

Override to add custom empty-state handling:

window.boostWidgetIntegration.extend('FilterRender', (FilterRender) => {
  return class extends FilterRender {
    removeDomFilterOptionIfEmpty(rawAction, option) {
      super.removeDomFilterOptionIfEmpty(rawAction, option);
      if (!option.values?.length) {
        console.info('Empty filter removed:', option.filterOptionId);
      }
    }
  };
});
