Support: CloseSubformButton in subform layout set

[lassopicasso]

Description

When setting up a subform, users need a close button that will close the subform and redirect them back to the associated main form.

To implement this, we can utilize our custom button feature. A switch button should be displayed at the top of the configuration on the subform layout page, just below the page ID. When the switch is activated, a custom button will be added to the component list for that page, configured as follows:

"id": "<some-generated-id",
"type": "CustomButton",
"actions": [
  {
    "type": "ClientAction",
    "id": "closeSubForm",
    "validation": {
        "page": "all",
        "show": ["All"]
      }
  }
]

Users must be able to define the button text, with a default text provided initially. If the button is removed from the component list, the switch should be turned off.

This functionality should allow for a switch button for each page in a subform.

Additional Information

Tasks:

• Add a Switch Below the ID: Implement a switch labeled "Legg til lukk underskjema knapp" below the ID on the layout page.
• Display and remove Custom Button: Ensure that when the switch is activated, the custom button appears in the layout page component list. When the switch is turned off, the custom button should be removed from the layout page. This functionality should also apply when dragging and dropping a custom button onto a subform page.
• Add/Delete Configuration: Implement the addition and deletion of the custom button configuration as outlined above.
• Default and custom button text: Allow users to define the text on the custom button, while also providing a default text initially.
