I am trying to have an expandable menu each time it's clicked expands, and
if it's clicked again, if it is already expanded contracts, and if
contracted expands, following this example
http://www.dynamicdrive.com/dynamicindex1/navigate1.htm, I notice the
example works in each sub folder and folder, it contracts and expands if
it
is already contracted/expanded, what do I add to this: <a
href="javascrip t:ddtreemenu.fl atten('treemenu 1services', 'expand') ?
ddtreemenu.flat ten('treemenu1s ervices', 'contact')" to cause the same
effect?
The javascript in simpletreemenu is:
var persisteduls=ne w Object()
var ddtreemenu=new Object()
ddtreemenu.clos efolder="/includes/closed.gif" //set image path to "closed"
folder image
ddtreemenu.open folder="/includes/open.gif" //set image path to "open" folder
image
//////////No need to edit beyond here///////////////////////////
