Syntax for oh-repeater on props

I am working on a personal widget where you enter in props settings a comma-separated value.
Now I want to build an oh-repeater on props parameters (e.g. prop_1, prop_2, prop_3, …)

...
config:              
  fragment: true
  sourceType: range
  for: buttonLabel
  rangeStart: 1
  rangeStop: 6
...
      component: oh-button
      config:
        text: =???
                        

text needs to be a concatenation of props.prop_ + loop.buttonlabel.toString()
What is here the correct syntax assuming the props are named prop_1, prop_2, prop_3, …?

As an alternative I tried to list the props directly in the in parameter:

...
config:
  fragment: true
  sourceType: array
  for: buttonLabel
  in:
    - props.prop_1
    - props.prop_2.toString()
    - =props.prop_3
    - ...
     
      component: oh-button
        config:
          text: =loop.buttonLabel.split("=")[0]

obviously none of the above props.prop1 is correct.

Anybody has got a clue about the correct syntax?

=props['prop_' + loop.buttonLabel.toString()] assuming sourceType: range like in your first example.

that was also on my list of hundreds of attempts :slight_smile:
unfortunately it does not work.
