Great, thanks, worked nicely. Now, is there a list with Concrete5 handlers I can use, such as 'replace_link_with_first_in_nav' for example?

Thanks,
Cristi

Sure is:

What about second child? Or any other arbitrary child within the navigation structure?
My tree looks something like this:
Home
|_Work
|_Visual Marketing
|_vm1
|_vm2
Now, I want Work to point directly to vm1. Initially, with only Work and Visual Marketing, when using 'replace_link_with_first_in_nav' worked perfectly. Then, I added vm1 under VIsual Marketing and tried to sett up Visual Marketing to use the same attribute to point to vm1. There for, when clicking on WOrk ti will point to first child, then the first child will point to secodn one.
Of course, didn't worked :)

Now What?

Thanks,
Cristi

I think you need to "add external link" in the sitemap, and put in the url for the appropriate child page there. (The "replace_link_with_first_in_nav" is just a convenience for the most common use case, and as such is very simplistic.)

I've used an external link:
http://www.thor9.com/index.php/visual-identity1/vi1/...

Now, Work points to taht address, second child. The only problem is that by doing this I lost the navigation class system. I do not have a class="nav-selected" .

What now? :)

Thanks,
Cristi

Well, I think you've reached the limits of what Concrete5 can do for you out-of-the-box :)

At this point you're talking about custom functionality. You would need to create a custom attribute for pages that allows you to enter another page as the redirect location.

This thread talks about that:

That may not be a complete solution (I have never done this myself so I don't know), but you could try searching the forums some more for another solution that is more complete.

Good luck!
