Support dynamic choices

[jaecktec]

Actual Situation

I'd like to ask for some choices (my case aws-regions) and in the second step I want that the user selects the primary region from the previously specified region.

Sadly the choices field is not evaluated as expression

Desired Situation

What happens right now:
the String is destructed as an array and I can chose a letter from my expression

What should happen:
The user should have a way how to dynamicly specify the choices

Proposed solution

I'd like that this works:

list_input:
  type: str
  help: "Enter a comma-separated list of items."
  default: "item1,item2,item3"

selected_choice:
  type: str
  help: "Select one of the items from your list."
  choices: "{{ list_input.split(',') | map('trim') | list }}"

The request for dynamic choices has come up a few times. We have a design proposal that looks promising. Would you happen to be interested in attempting an implementation?

the design proposal is coincidentially the same as my proposal :D

I most likely won't find the time the next months, however if nobody has attempted a PR I'll look into it

Ah, yes, of course, I had a Jinja for-loop with explicit YAML list syntax in mind, but you're right. 👍
