Conditional visibility with variables?

I want to create a stepper that allows only one option to be selected at the time using variables. So far I have something like this but it doesn’t feel clean or practical enough, since there I was trying with only 4 options and the actual content would have +10 options sometimes.

Each dash has an active/inactive version, and I toggle the visibility using booleans to invert the items that are being shown each time.
