I haven’t been able to make a ton of headway on this as a novice. I found a post on building tabs How to build the tabs in UI Builder that might be helpful. I think it all has to do with the Class List Logic, so I am playing with that.
PS. I would love if the table of contents of videos (Backendless For Developers | Backendless Backend as a Service Platform) had sub-topics listed under each title. Video content can’t be browsed and searched easily to find the 2 minutes you need in a sea of 15 minute videos. I think things like the names of the codeless blocks covered under each title would help adopters get up to speed more quickly. I am happy to try to find this stuff on my own but cannot find a way to do so efficiently. Eventually I’ll get through all the videos but I’m trying to put together a demo app simultaneously.
