//Version 1.1 (March 5th, 2010): Each flex menu (UL) can now be associated with a link dynamically, and/or defined using JavaScript instead of as markup.
|
|
//Version 1.2 (July 1st, 2011): Menu updated to work properly in popular mobile devices such as iPad/iPhone and Android tablets.
|
|
|
|
//Usage: $(elementselector).addpopupmenu('menuid')
|
|
//ie:
|
|
//jQuery(document).ready(function($){
|
|
//$('a.mylinks').addpopupmenu('popupmenu1') //apply popup menu with ID "popmenu1" to links with class="mylinks"
|
|
//})
