LuaGuielement ElemList tooltip type

[PennyJim]

Somewhat related to 77339 but smaller in scope, I want the ability to recreate the tooltip style used by furnace inputs, burner inputs, module slots, and maybe more.

Example tooltip on furnace input

I can see it either being an elem_tooltip type or a sister field, but it looks like it needs 3 parameters:

• Caption ("Ingredient" or "Module" for those tooltips) - maybe this merges with the element's regular tooltip and just uses that?
• Description:
  • "Possible Inputs:" (furnace)
  • "Fuel" (burner)
  • "Allowed modules:" (module slots)
• Elements - The list of elements to put in the grid. Maybe it only supports items or otherwise only one type at a time?

Looks like I forgot that EmptySlotInfo already supports caption and text (2 of the 3 components)

Since my use case is empty inventory slots, It makes sense to just add it there and hard-restrict it to items.

If possible, it would be nice to be able to describe elements as a list of ItemPrototypeName and possibly extra info. I would like to use this to reimplement certain UIs from pYanodons, particularly caravans and dig sites where food (fuel) can be inserted, and having a semi-custom or fully custom tooltips would be greatly appreciated to indicate to the player what fuels can be inserted and how effective they are.
