Disable top level enums
Good day everyone,
I need some assistance in disabling top-level enums. Let's say I have the following example
The top-level looks like this:
Then for each top-level entry, there are multiple other options:
I was hoping to achieve the following, or even better a combination of both:
A - Disable the top-level entry for being selected
B - If the user clicks on the top-level entry, automatically expand it so that they can select a child.
Any help or a nudge in the correct direction will be highly appreciated.
