Default Style
The default design features arrows on the side for all items with borders. This is similar to the Bootstrap menu design which is quite popular.
Clean Style
The clean design doesn’t have any arrows and uses a slimmer arrow style. This example has the drop-downs hidden so arrows only display on items with drop-downs for a toggle effect.
Plain Style
Similar to the clean design, but without the background hovers the plain design offers a more minimal design. The plain design also uses inline elements so you must hover over the text to click on a link.
