Question

Python

The image shows 3 switches (there may be a different number).
1 question
What elements are better to use in order to release this? The text inside will load differently and the stroke should be on the active switch accordingly.
Question 2
Is it possible to make a black outline of one of the switches using kv (preferably, of course, not on kv, but on python, but it looks like it won't work without it) or is it better to put an image?
