Filter Not work


I have work to cs cart v3. i add some products and check the filter price value. but not work the price value function. how to fix this problem?

I have a problem with creating a Product filter. I want to make it to filter by IN STOCK items , but when i want to select in the field Filter by : in the section Product fields there is no field In Stock. My question is HOW CAN I MAKE IN STOCK TO BE A PRODUCT FIELD ???

I'm using cs-cart v3.

Thanks in advance.

Same issue here, the filter is missing in CSC V3 Multi Vender to make filters by Vendor?

It says in the documentation on CS`s website that you can (Documentation/Products/Product Filters).
