When you click a Yes/No filter button in the search, such as the Pets filter, nothing appears to change. The selected option does not show visually, even though the filter seems active.
Why this happens. This is a visual display issue caused by a theme color conflict. The radio button registers the click correctly, but the selected state indicator (a dot) is painted white against a white background, so it is invisible. The filter is actually working. Only the visual feedback is missing.
How it is fixed. The fix is a CSS change specific to your site. Once it is in place, the Pets Yes/No buttons clearly show which option is selected.
