enableHeaderMenu style

What style parameters are valid for adjusting the display of the header context menu. I have a grid with many columns and when using this the context menu is many times the height of the grid. I’ve tried using set width, height, and overflow parameters in my css for .dhx_header_cmenu which I found in another post, but these parameters aren’t having any effect.

The height of menu set by js code, so it can’t be defined in CSS
By default menu takes the size, necessary to fit all elements, it is defined in

dhtmlxgrid_hmenu.css, line 101

You can update those line in necessary way.
