Only shoe current category subcategories

[MCanes]

Hi all.... Is it possible to modify Zen Cart so that it will only show the subcategories for the current category you are in at the left?

For example... Say I have 5 main categories when my site load - Cat 1, Cat 2, Cat 3, Cat 4 and Cat 5.

Under Cat 1 I have sub categories A, B, C and D and under sub category I have E, F, G and H.

Ok, now when someone visits and clicks on Category 1 I only want to show them A, B, C and D on the left. I am not worried about them getting lost because I also have a nav at the top with drop downs so they can easily navigate. I have like 30+ categories though and my page is so long for no reason.

Thanks in advance.

I killed that above... I meant to say...

Under Cat 1 I have sub categories A, B, C and D and under Category 2 I have sub category E, F, G and H.

You could use some of the logic developed in the Parent Categories Separated in 3 Sideboxes thread to accomplish this.

That checks whether the category is in a list of cats to display; you could check if there is an active category (i.e. $cPath != 0) and, if so, whether the top category being looked at in the sequence is active. Save the id of the active top cat, and on the following iterations check if the cats are subs of that top cat (i.e. start with [$active_top_cat_id]_).

This logic will display the full top cat menu on every page except when a cat has been clicked and you are viewing a particular cat and its subs.

Glenn,

Thanks for responding... Can you offer more guidance as I am new to Zen and PHP. You have been so helpful with some of my other requests and I appreciate it greatly.

I read the other post and I am still a bit confused on where I need to start and what I need to change to give this a whirl.

Thanks

I'll be happy to help, though I am likely to be away much of the time until Sunday night. If anyone else has ideas feel free to jump in.

If this works as I am envisioning, it will be a compact snippet of code and should be easy to drop in.

Thanks Glenn... I look forward to hearing from you, or anyone else for that matter that may be able to assist me.

It didn't seem to make any difference... Here is the code, did I type something wrong. I commented with my initials SPD. Thanks for helping.

It worked when I tested it... and I can't see any differences in your entry of the code.

Do you get any effect under any circumstances? Can you post a URL?

I just want the Arizona Cardinals and Auto Accessories to show. None of the other children under the NFL Category. Does that make sense?
