The label for a menu can be specified in one of four ways:

• putting a header tag in the menu
• setting the title attribute of the menu
• putting a header tag in the section containing the menu
• setting the title attribute of the section containing the menu

If none of these is done then jsLib puts in a "Missing Label" label which has styling similar to other types of errors. This type of error is illustrated in the menu to the left. The code file that produces this menu can be viewed by selecting the "Code" item in the menu.
