Seems you are working on a dynamic form builder where you can add different types or input elements for text, date, image, etc
Form
Title (text)
Field
Title (text)
Date value (date)
Number value (number)
Text value (text)
Image value (image)
Type (options set: date, number, text, image)
Form entry
Title (text)
Form (form)
Fields (list of fields)
Set up an rg of 1 row 1 column that is very high to accommodate your different inputs conditionally
Within the rg set up different groups stacked vertically and each accommodating a corresponding input element for date (date picker), number (input), text (multi line picker): image (image uploader).
Set each of the above groups to show up conditionally depending on the type of field
The rg is or type field and the data source is a search for fields constrained to the form entry which house the form object.
To see this in action you can test an app I built that has a dynamic form builder here:
