Adding my own tabs

how do I add my own tabs on the app. I’m trying to customize it so taht it matches the rest of my organization. how do I go about doing this.

All i really need is teh category and products section of the app… I dont need the top bar… etc. Ho do I go about making this happen?

Which file do I need to edit?

I highly recommended reading the manual at [URL][/URL]. Especially under the section Design | Blocks ([URL]CS-Cart Documentation — CS-Cart 4.15.x documentation)

The knowledge base at [URL]CS-Cart Documentation — CS-Cart 4.15.x documentation is also another place to become familiar with.
