An Equipment System based on available empty slots instead of categories

HI, I hope you’re doing well.

I have an issue with my UE5 project I was wondering you guys could help me with. If you have any ideas on how to do this, please let me know.

I watched this tutorial on Youtube:

It helped me create an equipment system for my game. Its a category based Slot widget creating inventory system that takes information for a Datatable. But currently, the slots allow for only one item per slot. And each slot has its own specific category it is allowed to fill.

I want a 3 slot equipment system that fills itself with the items in the inventory if a slot is open. If the slot is filled I want the next slot to be used and if all 3 are used I want it unable to add anymore items and tell the player so.

It would be similar to the Jetpack Joyride equipment system.

Would anyone
be able to help me with this?
