How can I display a menu on certain pages only?

Question

Instead of using sidebar widgets to tell on what page they should be visible, I like to choose at the menu settings to appear on specific pages.

Default Wordpress way:

So projects is a page and has some subpages. But what if I have like 10 more of these pages and subpages with the same situation.

I would like to add an extra setting (a list of the top level pages):

But I cannot find any documentation, actions, filters etc when these settings are loaded.

Answer 1

That's a nice option, but I agree with sri, right now it really depends on your theme. You can do a work-around through is_page(). You need to write something like this on your page.php theme file:

<?php
    if (is_page('projects')) {
        if ( is_active_sidebar( 'sidebar-navigation' )) {
            dynamic_sidebar( 'sidebar-navigation' );
        }
    }
?>

If you want to show the sidebar on other pages as well, you can use logic or like this:

if (is_page('projects') || is_page('home') || is_page('post-page'))

Answer 2

This is how you can do it in Twenty Twelve themes header.php copied to a child theme.

<?php if ( is_page('projects') ) : ?>
<?php wp_nav_menu( array( 'theme_location' => 'primary', 'menu' => 'conditional-menu-name', 'menu_class' => 'nav-menu' ) ); ?>
<?php else : ?>
<?php wp_nav_menu( array( 'theme_location' => 'primary', 'menu' => 'Primary', 'menu_class' => 'nav-menu' ) ); ?>
<?php endif; ?>

Create a new menu with the items you want to display and swap out the conditional-menu-name in the above code with the name of your menu.

menu_class names may need changing for themes other than Twenty Twelve.

I think using a plugin for this is better, so you can keep the functionality even if you change themes in the future. Check out this plugin. It does what you want, but slightly differently than how you mocked it up.

I know this thread is old but in case someone would need search for answer for this, I would like to suggest the conditional menus from themify https://themify.me/conditional-menus. You choose which menu to use, per page, category, meta, everything. and it is free :) hope this helps

If you are willing to re-engage your widgets and want a simple solution, you can use a plugin called Display Widgets. I have used this and use the text portion where you can add links to where you want to go. It works whether the links are on you own site or to another site. It has a space down below the text where you can choose which pages to show or hide. You can still remove the widgets that you do not use.

I played around with the menus for quite a while before I looked for and found this plugin. It works well.

You can find it in the Plugins section of WordPress.org.

One option would be to make custom templates for each menu that you have. (That refers to the theme locations check box) Then on every page, you choose the template that you want it to use and it will also use the menu associated with that template.

It gives you the same result I think you are looking for but rather than telling each menu what page it shows on, you will be telling each page what menu will show on it. An added benefit of doing it this way is that there is no way for you to accidentally tell two menus to be in the same place at the same time.

You can use Menu Swapper plugin for doing same thing from admin panel. Here is the Demo of this plugin.
