To reproduce the same Advanced Search as on our demo website, you just need to enter the shortcode into the SiteOrigin Hero slider like:
[ept_advanced_search visible_fields="price,bedrooms" advanced_fields="es_type,es_category,es_feature,es_amenities,bedrooms,bathrooms"] where
visible_fields are the fields that you can see at once when the page has been loaded, and advanced_fields are the fields that you can see only when clicking on More options link.
You can also use Estatik Search widget and add it to your page sidebar or use Estatik Search shortcodes to add search right into the page. Please check the details here.
