How are you creating the grids? Can you send a screenshot?

Yeah sure. For what it's worth, this is a pretty slick plugin you have here.

I'm still in the super early stages of putting it all together, so screenshots illustrate a hard-coded set of inventory icons in 3 groups and 8 icons each, but at some point this will be entirely dynamic based on a character that can have an un-bounded set of items that will grouped by category (swords, axes, bows, etc). So each group (grid) needs to be a wrap box that is sized so that only 5 icons can fit before wrapping. This aligns with the Dimension X of the 2d grid. So it's:

<verticle box>
   <header>
   <hr>
   <wrap box>
      <nav button>
      <nav button>
      ....
   </wrap box>
   <header>
   <hr>
   <wrap box>
      <nav button>
      <nav button>
      ....
   </wrap box>
   ...repeat...
</verticle box>

This actually works out very well. This only thing is, I had to adjust the c++ code to make it work. I found the original 0 button parameter enforcement unnecessary. This works just fine:

void UUINavWidget::AppendNavigationGrid2D(int DimensionX, int DimensionY, FButtonNavigation EdgeNavigation, bool bWrap, int ButtonsInGrid)
{
	FButtonNavigation NewNav;
	FGrid NewGrid = FGrid(EGridType::Grid2D, UINavButtons.Num() > 0 ? UINavButtons[NumberOfButtonsInGrids] : nullptr, NavigationGrids.Num(), DimensionX, DimensionY, EdgeNavigation, bWrap, ButtonsInGrid);
	...
}

Thanks for the compliment 👍
So if you call the functions the way you do in the screenshot and without modifying the AppendNavigation2D function, what happens?

Oh ok I get what the problem is 👍
I'll take care of it!
