Specifically, how would I do this without any JavaScript?
I have a RadMenu that I made 1080px wide, I have about 7 items in it so they only take up about 2/3 of that width.
I want force the items to split the width of the whole RadMenu between them so there's no awkward blank area on either side. (Similar to using Justify on a RadTab)
Can this be achieved with CSS, or existing functionality of the RadMenu?
You'll have to play with the padding element of the RadMenu and adjust the right and left side to get the desired with you want.
Remember the order is top, right, bottom, left.
