My hot slot widget blueprint has child widget blueprints for each individual slot. If i drag drop sth onto the hot slot grid - it casts an OnDrop event and the object is returned to inventory. If I drop it on a single slot widget - it casts an event to bind the object in it. The problem is when i drag drop payload on my slot blueprint - it casts both OnDrop events, so one object binds to a slot and also returns to inventory. What can I do to make the OnDrop event only be triggered on the top layer widget?
