<p>I have a Wordpress theme, where I would like to add a dropdown (select) menu in mobile view. I add the code in the header.php, the function.php and the jQuery in my custom.js file.</p> <p>It works very well (it's linking the url, it's clickable) if a menu exist on my "mainNav" menu section in WordPress.</p> <p>But if I turned off the menu, I get 2 notifications to the Developer Debug Bar plugin. "Notice: Trying to get properties on a non object" in line 45 and 50.</p> <p>Here's my code: <a href="http://i.stack.imgur.com/uNqru.png" rel="nofollow">http://i.stack.imgur.com/uNqru.png</a></p> <p>I think maybe if the navigation menu was empty, the values was empty, or nulled, but i don't know how the hack I correct it. Can anybody help me please? Thank you!</p> <pre><code>//DropDown Select Navigation for the Main Menu function wp_nav_menu_dropdown( $args = array() ) { $defaults = array( 'theme_location' => '', 'menu_class' => 'mainNav', ); $args = wp_parse_args( $args, $defaults ); if ( ( $menu_locations = get_nav_menu_locations() ) && isset( $menu_locations[ $args['theme_location'] ] ) ) { $menu = wp_get_nav_menu_object( $menu_locations[ $args['theme_location'] ] ); $menu_items = wp_get_nav_menu_items( $menu->term_id ); ?> <select id="menu-<?php echo $args['theme_location'] ?>" class="<?php echo $args['menu_class'] ?>"> <option value=""><?php _e( 'Navigation Menu' ); ?></option> <?php foreach( (array) $menu_items as $key => $menu_item ) : ?> <option value="<?php echo $menu_item->url ?>"><?php echo $menu_item->title ?></option> <?php endforeach; ?> </select> <?php } else { ?> <select class="menu-not-found"> <option value=""><?php _e( 'Menu Not Found' ); ?></option> </select> <?php } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
