Drag multiple items at once (without a grouping container)

[marktoman]

I use a sortable list of items. Multiple items can represent the same type. When two or more items of the same type are next to each other, I'd like to drag them together as a unit. I need to avoid using a grouping container because each item acts as a separate unit in other cases (e.g. an item of a different type can be dragged in between and split the set).

Is this achievable with DnD Kit? I've assigned setActivatorNodeRef of the sibling items to the leading one as a test, but it doesn't work.
