I did something similar..found it difficult to work with the default

But found it hard, when writing my own group snippet, to identify the
current Loc within the LocGroups Locs.
It's been a while since I wrote this, so don't recall if there any
issues, but this is my group snippet:
def group(template:NodeSeq) : NodeSeq = {
val toBind = if ((template \ bind).filter(_.prefix == menu).isEmpty)
xml:groupmenu:bind/ /xml:group
else
template
val attrs = S.prefixedAttrsToMetaData(a)
for (group - S.attr(group).toList;
siteMap - LiftRules.siteMap.toList;
loc - siteMap.locForGroup(group);
req - S.request;
curLoc - req.location;
link - loc.createDefaultLink;
linkText - loc.linkText) yield {
val a = (if (inPath(loc, curLoc.breadCrumbs)) span{linkText}/span
else a href={link}{linkText}/a) % attrs
Group(bind(menu, toBind, bind - a))
}
}
So Jeppe, would be very interested in your code for that snippet. Mine
is below (only slightly modified from Menu.group). But it's not yet
quite there.
I also used Menu.group as a starting point.
I also had a fiendish problem (lift 1.0.2 scala 2.7.5) when trying to
use attributes li:class=x li_item:class=y on the tag. Isn't that a
standard technique? Does it work for everyone else? For me, Scala
chokes on that with a syntax error (further experiments suggest that
it doesn't like two attributes with same name and different prefix,
perhaps also because BOTH prefixes are from an unknown namespace). Of
course it doesn't show you the exact error but faults with an
IllegalArgumentException on scala.io.Source, but this has been
discussed elsewhere. Anyway, that's why I have the new unprefixed
attributes in the code below.
Actually, I think I reported this as well and this works now (at least
in 1.1-SNAPSHOT). If possible, you should upgrade to 1.1 since the error
reporting has improved a lot. The IllegalArgumentException error you see
is not the root cause in your code, but an error that happens when
trying to show the source of the error !

[Lift] Re: Tabs + menu builder
It would be pretty easy to write your own snippet and get inspired from Lift's menu snippet code.THe Menu snippet produces lists (ul/li) and if your JQuery Tab plugin works with HTML lists it should work almost on the fly?

[Lift] Re: Tabs + menu builder
You can use lift:Menu.json/ to create a JavaScript variable called lift_menu that contains all the menu items. You can then use client-side JavaScript to read the objects and construct whatever menu you want.
