Cannot drop dataview object in layout cell after resize cell

Hi, I built a layout with 5 cells, each cell define a document category, and inside each cell there are a number of dataview that are the documents.
I need to do drag&drop to assign the category to a document.
When I drag in a cell that have documents inside it works, but if I drag a document (dataview) inside an empty cell I cannot drop. This bug seems happen when I resize the empty cell (in that case when I expand).
For a demo look at:

Hi,

What should be do to recreate the problem ?

Thanks Alexandra,
if you drag from the main cell in the right to the first and second cell you are able to drop, but if you do that for the other cell in the left you can’t drop the element.
Another example is that if move all 5 element from cell “1-Polizza” to the right the cell become empty, so if you collapse and expand the cell “1-Polizza” you can’t move the element inside.
Is it clean?

What is “1-Polizza” cell?

There are two open cells of layout: left cell and right cells. I have managed to drag elements from the left cell to right one and vice versa.

Please attach the working demo to the post and provide the detailed instruction how to recreate the problem.

I will try to explaine better how to reproduce the problem:

Work
1- Expand the cell “1-Categoria 1”
2-move using drag&drop all element from “1-Categoria 1” to the main cell in the right
3-when the cell “1-Categoria 1” become empty you che move some element of the main cell in the right inside the cell “1-Categoria 1”

Doesn’t Work
1- Expand the cell “1-Categoria 1”
2-move using drag&drop all element from “1-Categoria 1” to the main cell in the right
3-collapse and after expand the cell “1-Categoria 1” end try to move some elements inside, you can’t

The bug appear when you resize/collapse/expand a cell.
Is it clean?
Thanks very much.

Remove height “auto” from the dataview definition. It can not be used in the component is attached to another container:

data0 = dhxLayout.cells(“c0”).attachDataView({
// height: “auto”,

data1 = dhxLayout.cells(“c1”).attachDataView({
//height: “auto”,

Thanks very much!
