hierarchical jump menu? Is it possible?

[StephenKay]

I could swear I've seen (on some vBulletin Sites) a hierarchical jump menu - or am I crazy?

After upgrading to 3.7.0 this week, I was sort of expecting to find it as a feature/option, but it seems not.

Just to be clear, my jump menu presently looks like this:

Forum Category 1
    Sub-Forum 1
    Sub-Forum 2
    Sub-Forum 3
        Sub-Sub-Forum 1
        Sub-Sub-Forum 2
Forum Category 2
    Sub-Forum 1
    Sub-Forum 2
        Sub-Sub-Forum 1
        Sub-Sub-Forum 2
    Sub-Forum 3    ...etc.
Forum Category 3

...when what I'd like to see is (with forum category 2 selected):

Forum Category 1 >
Forum Category 2 >   Sub-Forum 1
                     Sub-Forum 2 > Sub-Sub-Forum 1
                                   Sub-Sub-Forum 2
                     Sub-Forum 3 
Forum Category 2 >
...etc.

...like a typical windows or mac hierarchical menu.

Is there a feature/hack/add-on for this, or am I just mistaken? I tried asking at vBulletin.org, but no reply so far. Thanks.
