Dropdown For Child Menu Links

I’m glad you like it.

The dropdown is an interesting idea. I’ll take a look at the possibilities.

Super stuff. I asked a dev friend of mine and he wrote something.

All you have to do is change “menu_in_post_menu” TO “menu_in_post_dropdown” in the shortcode

// ================================ START ================================

add_shortcode('menu_in_post_dropdown', 'menu_in_post_output_dropdown');
function menu_in_post_output_dropdown($atts = array(), $content, $shortcode_tag) {
	if (isset($atts['menu'])) {
		$menu = absint($atts['menu']);
	} else {
		$menu = 0;
	}
	if ($menu == 0) {
		return menu_in_post_fallback_fxn();
	} else {
		$args = array('menu'=>$menu, 'fallback_cb'=>'menu_in_post_fallback_fxn', 'echo'=>false);
	}
	// If menu_id is empty, don't pass a value, and the menu slug with an incremented value added will be used. 
	// If container_class is empty, don't pass a value and 'menu-{menu slug}-container' will be used.
	$defaults = array(
			'menu_class'=>'menu',
			'menu_id'=>'',	
			'container'=>'div', 
			'container_class'=>'', 
			'container_id'=>'', 
			'depth'=>0 
		);
	$search = array('<script>', '</script>', '<?php', '?>');
	foreach ($defaults as $att=>$default) {
		switch($att) {
			case 'depth':
				if (isset($atts[$att])) {
					$passed_depth = absint($atts[$att]);
					if ($passed_depth > 0) {
						$args['depth'] = $passed_depth;
					}
				}
			break;
			// These should be only strings.
			default:
				if (isset($atts[$att])) {
					$passed_att = filter_var($atts[$att], FILTER_SANITIZE_STRING);
					if ($passed_att != '') {
						$args[$att] = $passed_att;
					}
				}
		}	
	}

	return print_menu_shortcode($args, $atts['menu']);
}

function print_menu_shortcode($atts, $menuId) {
	extract( shortcode_atts(
		array(
			'name' => null, 
			'class' => null
		), 
		$atts
	));

	// Assuming $name contains slug or name of menue
	$menu_items = wp_get_nav_menu_items($menuId); 

	// Sample Output. Adjsut as per your exact requirements.

	// Sample Output variable.
	$menu_dropdown  = '';

	if ($menu_items){
		$menu_dropdown  .= '<select onChange="document.location.href=this.options[this.selectedIndex].value;">';

		foreach( $menu_items as $menu_item ) {
			$link = $menu_item->url;
			$title = $menu_item->title;
			$menu_dropdown  .= '<option value="' . $link .'">'. $title . '</option>' ;
		}

		$menu_dropdown  .= '</select>';

	} else {
	$menu_dropdown  = '<!-- no menu defined in location "'.$theme_location.'" -->';
	}

	return $menu_dropdown ;
}

// ================================ END ================================

I just put # for container and stacked in wordpress menus as you normally do.

Maybe this is helpful?

Should have said for the benefit of others who might read that it goes in functions.php

I added the dropdown functionality but for some reason subversion failed to include some necessary javascript files. Working on it…

I think I have that little issue with subversion straightened out with version 1.1.1, and all the necessary files are there now. I added backward-compatibility in v. 1.1.2, so that’s the current, stable version.

I could think of two options to provide a dropdown option:

1. Use CSS to style the unordered list as a dropdown
2. Add some javascript to navigate to the page using a select element

I think the CSS approach is too cumbersome and likely to cause too many theme conflicts, so I went with option two. You select the menu style using the Menu In Post Shortcode Builder, or you can add:

style="dropdown"

to an existing shortcode to change the style to dropdown.

Please give it a whirl and let me know what you think.

Works great for me!

Super useful the idea that a person can create the menu in the backend of the site as they need no expertise to add/edit code.

Can just create a menu link and paste that in. Anyone can do that.

Did you end up using the code? I’ll tell my friend if you did.

Great! I’ll mark this as resolved.

No, I appreciate it, but I didn’t use the code. I created a custom walker class to use with wp_nav_menu(), which allows you to pass the walker to build the menu. Same result, but a little more WordPress-ey, and allows the use of both the list and dropdown with the same code, basically.
