@JamesBoadi, I'm currently working on the first pass of this

Hey James, take a look at #850.

Are you able to create the designer side of this? at the minimum I would need an option to create a new page with repeatingFieldPageController.

This page should also should not allow more than 1 input component. worth giving it a try if this works with date parts field, but I doubt it, so please also restrict fields that render more than one (I think just date parts field, month parts field and address component).

here's a sample JSON sample for a repeatingFieldPageController

    {
      "path": "/which-languages-do-you-provide-a-service-in",
      "title": "Which languages do you provide a service in?",
      "controller": "RepeatingFieldPageController",
      "components": [
        {
          "name": "languagesProvided",
          "options": {
            "hideTitle": true
          },
          "list": "languages",
          "type": "AutocompleteField",
          "title": "Language",
          "hint": "List any languages you interpret or translate (apart from English)",
          "schema": {}
        }
      ],
      "next": [
        {
          "path": "/what-services-do-you-provide"
        }
      ]
    },

Yes i'm halfway through creating it, so repeatingFieldPageController will show a preview of the component in the designer once a new page is created?

And should this feature be unique to one component or reusable across all input components?

yes, should just look like a normal page. just that when you are creating a new one, you should be able to select repeatingFieldPageController.

And should this feature be unique to one component or reusable across all input components?

no. any number of repeatingFieldPageController can be created per form
