I like to get creative with multiple relations that link a row back to itself. This lets me create different single row inline lists that can perform a variety of different functions.
The red ‘X’ is part of an inline list in the Cards Style. I use it with a Set column action to set a value in that row, which closes (hides) the components above it. You could do something similar that shows or hides a hint component for example.
Here’s the app. Just try some of the blue memory buttons to see what I mean.
