[ic] Interrelated product options?

[Thomas Johnson]

Hello,

I'm trying to set up some product options that are dependent on each
other. For instance, I have brand X shoes in white, sizes 7,8,9 and in
black sizes 5,6, and 7. I'd like to give the user the option of picking
the color & size on the flypage, preferably something like this:

white <drop-down for 7,8,9>
black <drop-down for 7,8,9>

I know I could code this up in Perl with some SQL queries, but is there
a better way to do it that uses minimal Perl?

Thanks
Thomas
