How can I make toggle switch with checkboxes in After Effects?

[Moistoff]

I have a simple task, it is necessary that when one checkbox is on, the rest are turned off according to the toggle switch principle, how to create this using expressions in After Effects?

You can't. Checkbox controls are read-only and cannot be modified from within the expression. You have to think of another method. Explaining what you are actualyl trying to do might allow us to advise.

If you're trying to simulate a set of radio buttons (only one can be on at a time) a Dropdown Menu Control is often a workable alternative.

This works:

if (effect("Checkbox Control 2")("Checkbox") == 1){
	0;
}

else{
	value
}

As long as Checkbox 2 is not selected (checked), the Checkbox with this expression can be on or off. If you select Checkbox 2, the checkbox with the expression will be turned off.
