if you would like to see an example of what i am trying to do: http://edwardsmark.com/proofOfConcept/jqxwidgets/menuUpOrDown/menuUpOrDown.php?type=
notice i have 1000 items, yet all of them conveniently fit on the screen? (oops click the superfish option first please). i took superfish and made some modifications to it using the onBeforeLoad option. jqxwidgets could not do this, or at least not without thousands of $$$ to improve it.
speaking of $$$, if you can do something like this, i may have to purchase smartmenus premium support even before its offered.
