The Woo Filter By Price Element is designed to filter products based on their price. This element will be used in conjunction with the Woo Filter Active Element, and potentially one or more of the other Woo Filter Elements, the Woo Filter By Attribute Element, and/or the Woo Filter By Rating Element. These filters would typically be found in a sidebar on a shop page (try using a sticky column), where you could use the filter elements to filter the shop products.
The Woo Filter by Price Element only requires styling, and products that have a price to work.
IMPORTANT NOTE. These filters are for advanced users and need to be added to a Layout Section, as they are Layout Elements. They also only work with Archives.
So, to make a filterable shop page, or a Product Categories page, create a Layout, and set the conditions to be Archives > Product Archives Types, and / or Archives > All Product Categories. Then create a Content Layout Section, add your Woo Products with the Post Card Archives Element, using the Post Card of your choice, Post Cards Display set to Posts, and on the Layout Section Options tab, set the Archive Type as Products.
Then you can add the Filter Elements in a Sticky Sidebar. Depending on the attributes of your porducts, the various Filter Elements could be used.
