Changing the radmenu css class(rmSlide) dynamically

[ravi shankar]

Hi Telerik,

I am using radmenu control in my website which has 3 items namely podium,office and the forum as the top navigation items.all the top navigation items have subitems with different font,color,background image.

I want to change the rmSlide class for each top navigation item.So that Podium  uses rmSlide,The Office uses rmSlide1 and The forum to uses rmSlide2.

all the 3 dropdown has diffrent bg example podium(pink),office(blue) and the forum(brown).

So Please help me to solve this issue.
