Change Primary Navigation with Page

[kimberlymwhd]

Can you change the Primary Navigation menu for each individual Page?

I tried this with Genesis Simple Menu and its only for Secondary Menu.

I want to have 5 Custom Menus for 5 different Pages.

Let me know if anyone can walk me through how to do this. Thanks!

If you want to use the plugin, I would suggest switching out the location of the secondary menu for your primary menu, and voila, you can use that plugin 🙂

Otherwise, you can hard code your functions.php file to display a different menu on different pages.

Susan, everything I read said no one would support changes like that.

I see in the Plugin editor a bunch of things that say "gsm" assuming that means secondary? What would I change in there to make it primary?

Here is the code for the Plugin:

everything I read said no one would support changes like that.

I'm not sure why it would be an issue to change the location of your primary and/or secondary menu, since in some themes, support for the primary and secondary menus are completely removed anyway?

I found a couple of posts on Brad Dalton's site (here) about a number of ways of accomplishing what you want to do.
