First, add the Link to Screen action in your component's settings.
You can then choose what data will appear on the screen you are linking to. The linked screen's data can come from:
The current item
Another sheet in your app
When you click through to that screen you'll be able to customize that screen's layout however you like. This layout will remain unique to this particular link-to-screen action – meaning that you will be able to link to the same screen multiple times and show that screen in different ways.
If you have created relations in your table, then you will be able to choose those relations as the source for your new screen. This acts very much like a List Relation – apart from the fact that every screen you link to can be uniquely designed.
This initially may sound strange (why would you want to show the same item/row you are on?) but when you consider that the screen you link to can be configured independently of the screen you link from, then it makes sense. In the app below the Link to Screen acts as a 'read more' function - enabling us to show more of the current row when the user taps into the next screen.
Linking to another sheet acts just like adding a new tab and picking a sheet. Once you've picked the sheet and clicked through to the new screen you'll be able to customize that screen with its own layout.
With the Link to Screen action, you can create custom menus instead of or in addition to tabs. Here you can see an example of our Glide Community app which only has two tabs and uses
Images as it's a navigation system.
