This routine wraps a menuitem in proper HTML. It is used by primary_menu() and
secondary_menu().
=item primary_menu()
-This routine evaluates @primary_menu and returns XHTML for the menu
-that contains following links: About, Message, Roles, Help, Logout
+This routine evaluates @primary_menu and returns a two item array,
+with the array elements containing XHTML for the left and right sides of
+the menu that contains the following links: About, Message, Roles, Help, Logout
@primary_menu is filled within the BEGIN block of this module with
-entries from mydesk.tab
+entries from mydesk.tab
=item secondary_menu()
Same as primary_menu() but operates on @secondary_menu.
+=item create_submenu()
+
+Creates XHTML for unordered list of sub-menu items which belong to a
+particular top-level menu item. Uses hover pseudo class in css to display
+dropdown list when mouse hovers over top-level item. Support for IE6
+(no hover psuedo class) via LC_hoverable class for
tag for top-
+level item, which employs jQuery to handle behavior on mouseover.
+
+Inputs: 6 - (a) link and (b) target for anchor href in top level item,
+ (c) title for text wrapped by anchor tag in top level item,
+ (d) reference to array of arrays of sub-menu items,
+ (e) boolean to indicate whether to call &mt() to translate
+ name of menu item,
+ (f) optional class for element in primary menu, for which
+ sub menu is being generated.
+
+ The underlying datastructure used in (d) contains data from mydesk.tab.
+ It consists of an array which has an array for each item appearing in
+ the menu (e.g. [["link", "title", "condition"]] for a single-item menu).
+ create_submenu() supports also the creation of XHTML for nested dropdown
+ menus represented by unordered lists. This is done by replacing the
+ scalar used for the link with an arrayreference containing the menuitems
+ for the nested menu. This can be done recursively so that the next menu
+ may also contain nested submenus.
+
+ Example:
+ [ # begin of datastructure
+ ["/home/", "Home", "condition1"], # 1st item of the 1st layer menu
+ [ # 2nd item of the 1st layer menu
+ [ # anon. array for nested menu
+ ["/path1", "Path1", undef], # 1st item of the 2nd layer menu
+ ["/path2", "Path2", undef], # 2nd item of the 2nd layer menu
+ [ # 3rd item of the 2nd layer menu
+ [[...], [...], ..., [...]], # containing another menu layer
+ "Sub-Sub-Menu", # title for this container
+ undef
+ ]
+ ], # end of array/nested menu
+ "Sub-Menu", # title for the container item
+ undef
+ ] # end of 2nd item of the 1st layer menu
+]
