javascript - Using the following tree navigation script, how to make the heading trigger the drop down? -

-

we're using following script have dropdown navigation:

http://www.onlinetools.org/tools/dom-tree-menu-puredom/#

however, drop down triggered when [+] or [-] clicked. happen headings trigger dropdown. like:

[+] heading [+] heading 2 [+] heading 3

when click on [+] , word "heading" drop down list appear so:

[-] heading  -- content 1  -- content 2  -- content 3 [+] heading 2 [+] heading 3

currently, [+] triggers drop down , "heading" merely allows put normal link.

linkparent:false change linkparent:true

if change true have feeling allow heading linking too.

if take @ line 41 sets click handler. first tag [0] arrow , second tag [1] believe title

pde.addevent(parentli.getelementsbytagname('a')[0],'click',pde.showhide,false); parentli.getelementsbytagname('a')[0].onclick=function(){return false;} // safari hack if(pde.linkparent){     pde.addevent(parentli.getelementsbytagname('a')[1],'click',pde.showhide,false);     parentli.getelementsbytagname('a')[1].onclick=function(){return false;} // safari hack  }

hint: have nice comment in beginning of script.

// boolean make parent link collapse section or not       linkparent:false,
