isAllowed returns undefined for placeholderParent when dragging into root about nestedsortable

@Danita, are you dragging the node from a connected sortable list?

[Danita]

Oh, I reported this a long time ago... I don't really remember. Let me see if I'm still using the library in any of my projects 😄

[freddyamsterdam]

Yeah, didn't realise until after I commented. 😂

I'm interested with this. I use connected list.
I use two times nestedSortable :

• The 1st to manage category and subcategory on 2 levels (not connected)

• The 2nd to manage item (in these categories/subcategories), connected with css class on 1 level.

What I want is to drag item from a category/subcategory to another without be able to drop it in the root of the categories.

Dropping item in another category/subcategory is working but I can't prevent dropping in root of the categories.

Do you know how to do that ?

Ok. For you interest, take a look at this fork (in development) : https://github.com/CanopyApps/nestedSortable/tree/develop

It has "maintainNestingLevel" option when set to true does what I need.
Do you how to achieve this in our case ?
