A dropdown is an overlay window that displays lists or action links.

If different sections need to be shown, each section should have a label.

View “Menu section” for more information.

If a dangerous action is added, It should be in red and at the end of the list.


When users toggle a dropdown, the overlay window shall appear below the element that generates it.

If users click on a dropdown item or anywhere outside the window, the dropdown shall disappear.



Dropdowns are squares with a 1px grey outline and 4px corner radius. To make them stand out from the rest, they shall have a shadow.
