Morph is an easy-to-setup fly-out mobile menu for WordPress. While designed primarily as a mobile menu, it works wonderfully on both desktop and touch devices, and can be set to be shown at specified resolutions only, meaning – if you so wish – it can easily be used as a mobile-only or desktop-only menu.
Morph is also extremely easy to customize; by changing colors, enabling/disabling and modifying different elements, you can make sure your mobile menu suits your site. It even supports widgets, making it that much more expandable.
Furthermore, the fly-out menu can be triggered by any element (a custom menu button for example). All you have to do is add a specific class to the element and voila! For cases such as this, Morph’s own menu button can be hidden with a single click.
