Hi,
I am not sure if this is what you mean, but you can create groups for the properties you define in the template like this:
…
“groups”: [
{
“id”: “inputs”,
“label”: “Delegate Input”
}
]
…
And reference the group in the property with:
… “group”: “inputs” …
This will put all properties referencing this group in one collapsable section in the properties panel.
Now I get what you try to achieve but I don’t know of any way to let users add properties in the panel via templates. Sorry but hope you find a solution soon
