Access the index of current item in a group for a schema-defined generated form

[Taso69]

Hello everyone,

First of all, thanks for the awesome framework, this is an incredible job !

This might be a documentation request rather than a feature request : I'd like to use the index for the items inside a repeatable group. I can see how it would be done for a "classic" html-defined FormulateForm, but I need to do it from a JSON-defined schema, and {{ index }} doesn't work (and I don't think setting "default": "index" does anything in myGroup ? I don't exactly get how the default slot component may be used from within the JSON schema)

{
  "name": "myGroup",
  "type": "group",
  "repeatable": true,
  "default": "index",
  "children": [
  {
    "name": "myCheckbox",
    "label": "I am the checkbox {{ index }}",
    "type": "checkbox"
  }
}

Any ideas ? Any way to access the groupProps from the children ?

Hey @Taso69.

Hmm, not sure there's a good way to do this using a schema necessarily. We're trying to avoid putting expressions in the JSON since then we basically have to create a JSON serializable language 😂.

I'll think on this some as we work on version 3 though.

I achieved this by using a custom plugin/field, however, I'd love to see some basic show/hide logic in the schema though.

Perhaps something like this:

{
  "name": "Example"
  "show" "field_name:yes"
}

Where another field value makes this field visible or not.

We could raw influence from how laravel handles more complex validation rules.

Do you mind sharing how you did this?

Thanks
