[opencms-dev] menu help needed

[William Kernos]

Hey ppl I have been developing a small site with open cms but am now
struggling,

Based on a few examples & my very limited experience in coding I have come
up with the code below that does breadcrumbs & builds a sitemap. I now need
this modified to only print out top level menu options except if you are in
a sublevel menu in which case it needs to expand the menu option under only
the top level menu item that you are under.

 

For example:

 

Say your overall sitemap looked like

 

Folder1

            Page1

            Page2

                        Page3

Folder2

            Page1

            Page2

                        Page3

 

Then you clicked on Page 2 under Folder2 the staemap would look something
like this

 

Folder1

Folder2

            Page1

            Page2

                        Page3

 

If that makes any sense to you.

The only way I can see to do this is create a tree structure using the
navigation elements but I don't want to reinvent the wheel if there is an
easier way of doing it, or if someone has some code I could use.

Any help would be greatly appreciated.

Regards,

Will
