Thanks for posting! You can build a classifieds website with the built-in Classifieds app in UltimateWB Full software. The software does not come with design templates, but rather a Styles Manager to create your own template. You can read about how the Classifieds app works in the User Manual here: https://www.ultimatewb.com/classifieds-app/create-customize-integrate-classifieds-section .
