The layout of this demo mirrors that seen in my development team's application. It consists of a 2U layout with a scrolling set of DIVs in the right cell. These DIVs in turn contain a 3W layout, where each cell contains a 3E layout. The middle cell of each 3E layout contains a 1C layout. This demo differs from the previous one in that it contains a line of code provided by Andrei at the DHTMLX forums, which modifies the structure of the 3E layout to allow both of the bottom cells to be collapsed simultaneously. Unfortunately, this has presented another problem. In version 3.6 of DHTMLX and the previous demo, this layout displayed headers at the top of each of the 3W layout's cells, allowing the user to collapse each column of cells as a whole. However, when upgraded to version 4.0, these headers disappears. During construction of this demo, it was discovered that the cause appears to be the presence of the 1C layouts; if these are removed, as in this otherwise identical demo, the headers appear as expected.
You should see a header above this cell that allows you to collapse this column of cells... but it's not there.
If this inner 1C layout is not present, there IS a header in the cell above as expected. However, once the 1C layout gets attached, the header disappears and won't come back.
The change to the 3E layout does allow me to be collapsed along with the cell immediately above me, but causes the problem noted in the top cell.
