Hi,
I am looking at using Ajax Search Pro for filtering the Woocommerce Shop page. I do not want the search bar but I will use ONLY the categories / taxonomy. I want the shop page to change as I select the choices.
Unfortunately this is not possible. The plugin cannot affect the shop page layout, only its own search results.
It is possible to disable the search bar and use the filters only on the Layout Options -> Search box layout panel. This still not affect the shop page, but you can put it on a separate page to use it as a search filter.
