options: boolean | AddEventListenerOptionsCloses this menu, and calls .focus() on the element which triggered the creation of this. If this is a sub-menu, that would be the parent list-item. Otherwise it would be the linked element associted with the root menu.
This function also add the dropdown-closing
class to this element. If the animation
CSS property changes
after applying that class, then this element will become "inert" (not reacting to user input and allowing users
to click "through" this element) and will be finally removed after the animation finishes playing.
Closes the sub-menu if it is opened
Optional

Returns a HTMLCollection of the elements in the object on which the method was invoked (a document or an element) that have all the classes given by classNames. The classNames argument is interpreted as a space-separated list of classes.

User agents are always free to honor user preference over the application's. The default value "auto" indicates no application preference.
Optional

getthe root active menu if it exists
This is the menu which actually gets shown to the user. Represented by
<active-dropdown-menu>
in the document.It is automatically created and appended to the end of the
<body>
whenever a"dropdownOpen"
event is emitted without being cancelled. It is not intended to be created by anything other than this library.Creating a new element and appending it at the end of the body ensures that the full menu will still be shown even when defined within elements with the
overflow: hidden
CSS rule.When created, this uses the root
<dropdown-menu>
, along with any<dropdown-menu-inner>
elements as templates.It follows the same structure as a
<dropdown-menu>
, except all<dropdown-menu-inner>
elements are replaced with<active-dropdown-menu>
elements, and all<dropdown-menu-item>
elements are replaced with<active-dropdown-menu-item>
elements.For the purposes of CSS styling, here are some tips:
active-dropdown-menu-item:has(active-dropdown-menu)::after
to add a menu charm to hint at the existance of a sub-menu.active-dropdown-menu-item:focus
. Using:hover
is unnecessary.active-dropdown-menu-item:has(active-dropdown-menu:not([inert]))
to target a<active-dropdown-menu-item>
which has its sub-menu currently open.active-dropdown-menu-item[disabled]
to target a menu item that's disabled. the:disabled
pseudo class won't work.dropdown-upward
: the menu should expand upwarddropdown-downward
: the menu should expand downwarddropdown-leftward
: the menu should expand to the leftdropdown-rightward
: the menu should expand to the rightdropdown-closing
: the menu is about to be closed or removed. If any of theanimation-*
CSS properties change when this class is applied, then this element will not be removed until the animation finishes playing, unless the animation is set to play infinitely, in which case it is ignored. While the closing animation plays, this element will be set to "inert", allowing users to interact with the page as if the menu didn't exist.<active-dropdown-menu-item>
is activated, that is, if it was clicked on or if the enter key was pressed while it is focuses, then adropdown-selected
class will be added to the<active-dropdown-menu-item>
at the same time when thedropdown-closing
class is added to the<active-dropdown-menu>
. Note that this class will have no affect as to when the element is removed.
