It is clear that a layout cannot be nested inside an other layout.
In a previous post
@philmodjunk suggested a trick using a portal with one row.
I am in the process of adding an Help_table inside a solution and I would be happy to have more details about the above trick.
Specifically, in the Help_table my wish is to have specific help_layouts explaining each important solution_layouts using a portals, or Popover Buttons (don't know which should be better)
The idea is to reproduce inside the portal (or the Popover) the original solution layouts (in such case I would disable original buttons)
Well, I could do that saving a screenshot of each layout and adding the image inside containers of the Help_table, but doing any changes of the solution_layouts I would need to remake every screenshot...quite boring !
