First i would like to say new telerik site looks great. I like the way you have arrange related items in navigation. Here is a small suggestion on how menu items look on hover.
Hope this is useful enough.
.tSectionsNavWrap .mSubMenuInner ul |
{border-right:1px solid #484A50;margin:0px 0px 0px 16px; padding:0px 16px 0px 0px;} |
.tSectionsNavWrap .mSubMenuInner ul li |
{padding:3px 0px;margin:8px 0px;} |
.tSectionsNavWrap .mSubMenuInner ul li:hover |
{background-color:#21242c;} |
.tSectionsNavWrap .mSubMenuInner .col1 .mSubMenuMajorList li:hover |
{background-color:transparent;} |
.tSectionsNavWrap .mSubMenuInner ul.mSubMenuMajorList li a:hover, |
.tSectionsNavWrap .mSubMenuInner ul li span.mTxt a:hover |
{color:#a6ce39;background:none;} |
Hope this is useful enough.
