prevent dragging from onDragStart

[dwelle]

I need to prevent dragging based on the DOM element (tree) which the user started dragging.

The new RadixUI dropdown menu is being rendered inside the item (as opposed to a React Portal) which means that if you open a dropdown menu inside a draggable item it will allow to drag the whole dropdown menu. EDIT: it actually still applies even if the dropdown is portaled, because the event up the component tree.

I can hack it with the disabled flag but it's a lot of unnecessary work.

I'd be great if dnd-kit's onDragStart event contained the event.target and be preventable (.preventDefault()), or have some other mechanism to prevent the dragging.
