Hello,
WoodMart attribute filter is based on the default Woocommerce attribute filter functionality. As you know when you sort out the products, the products related to the attribute are shown.
There is a trick:
1. Enable “Enable archives?” for the brand attribute. All the brands would get the option to be viewed: https://prnt.sc/108kimf your brand page would look like this: https://prnt.sc/108kjkn
2. Create a menu in Appearance > Menu, include all your brand items by means of a custom URL
3. Add WOODMART Sidebar Mega Menu widget to the Shop page widget area and chose your menu.
When the customer clicks a brand, a page with the description at the top and products would appear.
Best Regards
