Thanks, that eliminated the borders and difference in color. I had to modify the following Resources
It looks much better, but it would be even better if I could eliminate the space which is still reserved for the icons. I.e. the space is still there, but it's now the same color as the rest of the menu items, so it looks like there is a very wide left margin on the submenus.
Visually, this looks OK, so I can live with this if eliminating the space altogether is difficult.
Thanks!
