As per weebly documentation weebly does not provide filter search for their websites.
One of the cool features of expertrec.com site search for weebly websites is automatic faceted search. Yea, Expertrec auto magically detects the facets on your products data and create facets for each of them.
So what are you waiting for
You should Enable facet Search at expertrec.com dashboard by navigating UI Customization > Facets
Whats more cool about expertrec facet search is you can customize what data about a product should be a facet.
You can add / remove / edit facets available.
All you get is for 9$, which is really worth the price. So what are you waiting for…
