Trying to create a single page native app with URL’s

Hi, I’m trying to create my first app (single page- native). I have my home page (Index) complete, but cannot figure out how to show/hide a page (group) from a clicked button (ie “about us” to navigate to that content). Every video I have watched on conditions/parameters has not led me to completing a successful workflow to establish it. I feel like the “elements action” to then “display data” has me going in the right direction??? Any help would be greatly appreciated.

Use conditions on groups based on url parameters. I can’t search forum now but if you do you’ll find threads with answers.
