I want the player to be able to rearrange weapons on his list mincraft/stardew style but I can’t find the BP node to move elements around in a horizontal/vertical/wrap box. Anyone familiar with this?
Very familiar, sadly. The functionality of inserting children into container lists is not exposed to BPs.
To pull it of in BPs
- keep widgets in an array
- swap array elements accordingly
- clear the widget container
- repopulate from the array
It’s not as inefficient as it sounds. The biggest drawback is slot formatting.

So I can place say, a horizontal box with 2 text boxes in a created named variable array and it will hold all the settings of the Horizontal box and all those text boxes, or am I unaware of the kind of array you are talking about?
You want to change the order of elements on the ability / inventory bar - widgets that sit in a horizontal box. Add those widgets to an array and reorder that array instead. That is your new order of elements.
Similar to this:
But rather then inserting at the start / end you can actually swap elements:

You asked about moving elements in a horizontal box directly, the above applies. However…
Normally, you approach something like this quite differently, you do not keep your abilities / skills / items directly in a horizontal box. You create additional widgets that serve as slots. So you end up with a horizontal box with 10 empty slots that can hold any widget you need.
Each slot implements onDrop. If you drop onto a slot that already has something, you swap things around. If you drop onto a slot that is empty, you simply add the widget to that slot, and it will be automagically removed from the other one since widgets can have only 1 parent.
edit: just to visualise, here’s what I mean:
It’s a widget with slots (more can be added dynamically, of course). The slots implement onDrop. While the abilities implement dragging.
