Labels layout cells


I am working with a layout 2E, the problem I have is that when a cell collapse clears the label that displays in the header of the cell.

Why does this happen?

Thank you. A greeting.


By the default layout up to 2.5 version does not supported text on collapsed cells.
Experimental support was added in 2.5+ version.

If you need to set text for vertical cell, you may use image with vertical text.
