I do not know if this will be helpful to anyone, but some time ago we
formatted the brain jar tag into a really simple custom tag. This is a
really bare bones menu tag, but does the trick and cleans up real well
if you tweak the CSS.
The CF code was done by Chris Kent and then a few updates here and there
to make it a tag by me. Any tweaks or thoughts are welcome.
Again a thanks to Chris my Jedi Friend!!!!
[Place in the header of template to whatever is your path to the css and js]
<link rel="stylesheet" type="text/css" href="/css/bjmenu.css"
media="screen" />
<SCRIPT type="text/javascript" src="/js/menu/bjmenu.js"></SCRIPT>
[Place _bjmenu.cfm in a folder of your choice and call in the tag
wherever you want the nav to show]
<cfmodule
template="/farcry/#application.applicationname#/webskin/includes/_bjmenu.cfm"
root="#application.navid.home#"
showHome="no"
delimiter=" | ">
[Two recommendations. 1) Do not wrap a cfoutput around the tag 2) If
your tree is big, cache the nav.]
