I would like to have a radio group where the size of the array is dynamic. I know I can use a script transform on the “radios” property, but I am not sure how to actually create the “radios” dataset. For example, I want to enter “3” and dynamically have a radio group with 3 buttons in it. Any ideas?

Use a transform. In this case I’m transforming the constant value `3` out of an expression, but it’d be easy to refer to a property elsewhere instead:

The transform is pretty simple:

```python
	return [
		{
			"text": "Button %s" % (i+1),
			"selected": False,
			"value": "Button %s" % (i+1),
		} for i in range(value)
	]

```

I learnt something new in Python today! from a post 7 months ago… 😄 specifically the for loop part to create things as you did
