AT:

• When hovering over a submenu item, the submenu is opened
• If the cursor is no longer over the submenu item or the opened submenu, the submenu is closed
• If the user clicks on a submenu item, it stays open even if the cursor leaves the submenu item or the submenu
• While a submenu is open because it has been clicked on, it is no longer possible to open other submenu items via hovering, as only one submenu can be open at a time
• A submenu that has been opened by clicking on the submenu item closes if the user clicks anywhere except the submenu or the submenu item
