@dgrammatiko @Fedik This is the question/issue I asked you two yesterday. Would be nice if we can come up with a solution (although I'm unsure if it is possible with the library we are using)

I wonder for what this option

seems does not make any difference

Guess that's used to prevent dragging an element from one group to a different group only. We do not have a way to move the whole group (parent and it's children) to new position.

@Fedik @joomdonation please read the commend at the beginning of the conditional, this is the fallback for B/C.

@dgrammatiko I think we understand that. @Fedik wanted to know if that could be used to solve the issue you are having here.

Do you think we can have a solution for dragula to handle drag and drop the whole group as we are having in J3?

FWIW at the drop event if the dragged element was a category parent I guess we could move all the children after it.
pseudocode:

// el the dragged element
Array.from(document.querySelectorAll(el.dataset.nested).reverse().filter(l => l !== el).map(
// move them under el...
)

I was thinking the same but that's beyond my JS skill :(.

please test #34584
