I have been working in this problem for weeks and I was determined to sort
it myself however I feel I need guidance to proceed forward.
What I am trying to produce is some asp code that can split categories and
group from a text string that is delimited by a "| ". (see string examples
below). I have managed to find some javascript that will handle the
different levels of categories without having to keep refreshing the page.
So I want the asp code to split the categories in the javascript array's
(see java code below) and be flexible enough to handle different numbers of
sub categories as they can vary.
Any guidance or examples would be appreciated.
Thanks
Sean

And this second example shows a pair of single-entry "combo"
