DropMenuPlus -- is just dropmenu with a small hack. If I remember correctly the hack was something that let's you get the parent of the current category or like that ... jeez, I should remember things like this!
// ###########################################
// DropMenu #
// ###########################################
// Configurable menu / navigation builder using UL tags
// Offers optional DIV wrappers for top level and nested menus (useful for hover zones)
// as well as configurable classes for the DIV, UL, and LI elements. It even
// marks ancestors of and the current element with a hereClass (indicating you are here
// and in this area of the site). Also applies .last CSS class to final LI in each UL.
//
// Developed by Vertexworks.com and Opengeek.com
// Feel free to use if you keep this header and credits in place
//
// Inspired by List Site Map by Jaredc, SimpleList by Bravado,
// and ListMenuX by OpenGeek
//
// Configuration parameters:
//
// &menuName - name of a placeholder for placing the output in the layout
// &topnavClass - CSS class for styling the class assigned to the outermost UL
//
// TO DO: configuration parameters above, more usage examples, CSS examples, output indenting
// ###########################################
// Usage Examples #
// ###########################################
// Creates menu with wrapping DIV with id=myMenu, starting at the site root, two levels deep,
// with descriptions next to the links, and nested UL elements with class=nestedLinks; output
// of menu can be placed in layout using placeholder named myMenu ( e.g. [ +myMenu+ ] )
// [[DropMenu? &menuName=`myMenu` &startDoc=`0` &levelLimit=`2` &topdiv=`true` &showDescription=`true` &subnavClass=`nestedLinks`]]
//
// Creates topMenu from site root, including only 1 level, with class=topMenubar applied to the top level UL
// and class=activeLink applied to current page LI
// [[DropMenu? &menuName=`topMenu` &startDoc=`0` &levelLimit=`1` &topnavClass=`topMenubar` &here=`activeLink`]]
//
// Creates dropmenu 3 levels deep, with DIV wrappers around all nested lists styled with class=hoverZone
// and currentPage LI styled with class=currentPage
// [[DropMenu? &levelLimit=3 &subdiv=true &subdivClass=hoverZone &subnavClass=menuZone &here=currentPage]]
//
// Creates dropmenu of infinite levels, ordered by menutitle in descending order
// [[DropMenu?orderBy=menutitle&orderDesc=true]]

// $textOfLinks [ string ]

// menutitle, id, pagetitle, description, parent, alias, longtitle, introtext
