Diffrent Width for Dirrent Menu Item

[dp009]

I am trying to make diffrent item of menu with diffrent width.

in config.js it says : "oCMenu.level[0].width=100 //The default width for each level[0] (top) items. You can override this on each item by spesifying the width when making the item. - Value: px || "%""

Here, What I do in menu-config.xml to create menu...
<Menu name="ToDoListMenuFile" title="FILE" description="test" width="50">
<Item name="TDLnewcase" title="CASE" width="80 px" location="NewCase.jsp"/>
<Item name="TDLnewitem" title="ITEM" width="110px" location="index.jsp"/>
<Item name="TDLnewparty" title="PARTY" location="index.jsp"/>
</Menu>

If someone know how to deal with this pl let me know!!

Thanks
