This plugin enables you to upload images for nav menu items on a menu edit screen. By default, those images will be displayed instead of text for respective menu items. Note that after upload, you should set an image as ‘featured’ to be able to display it.
You can also set images that will be displayed only when you hover menu item, or when menu item is of currently displayed page. <a href="http://blog.milandinic.com/wordpress/plugins/nav-menu-images/#how-to-use" rel="nofollow ugc">Read detailed instructions about using plugin</a>.
Developers can use many available filters to make their own way of displaying images, or even create a child class on top of base one. See source code for more ideas.
Although this plugin displays uploaded images out of the box, it will probably not give best possible look, so it’s recommended to create custom CSS styles for affected elements.

Nav Menu Images

Great and light weight plugin, without affecting core functionality of WordPress.



Code quality

Does what it's supposed to.
Would love the possibility to choose wether or not to replace all link content - would be nice if the link text would still be shown + adding a custom class to image.

Does what it promise

Works well.

When adding a page, category, or any hierarchical custom post type or taxonomy to your navigation menu (Appearance → Menus), this plugin allows you to optionally automatically add all descendants (children) of that menu item as submenu items.
In short, you’ll no longer have to manually maintain submenus when you add a new child page to your site.

Add Descendants As Submenu Items

Still works great. Much better than Gecka Submenu - it doesn't break the layout on the menu screen and there's no unnecessary pro version upsell.  I hope this is updated at some point because its age is hiding it from WP's search results.



Works great and it's clean

Automatically all of a nav menu item's descendants as submenu items. Designed for pages but will work with any hierarchical post type or taxonomy …
