Scaffold complex properties as a table element

Currently in Designer when scaffolding a complex property the sub properties are scaffolded individually as an element.

This is inconsistent with the drag and drop behavior that creates an element for the complex property itself.

TODO

• When scaffolding a complex property, create a table element for it

ACCEPTANCE CRITERIA

• When I scaffold a layout for a document that contains a schema with a complex property, a single element is created for the complex property
• The element is linked to the complex property
• I can click on the element and see an edit icon
• When clicking on the edit icon, the sub properties can be edited
