Just to demonstrate and to ensure I understood OP correctly. Imagine you want to cycle through several submenus:
You can add them to the switcher as custom widgets - so they are created automagically when the switcher widget is initialised.
And then you can cycle through any number of submenu children like so:
It generally works well. The only downside is having a slightly larger memory footprint as all the submenus reside in the memory at all times. Can be pretty much ignored unless you’re targeting mobile.
Apart from the ease of use, the other plus side is that these are instantiated early so you do not need to worry about auto-wrapped text flickering in front of your eyes. Or forcing a layout prepass to get rid of it.
Definitely worth trying.
Good luck!
