Constructor
new OO.ui.DropdownWidget([config])
#
DropdownWidgets are not menus themselves, rather they contain a menu of options created with OO.ui.MenuOptionWidget. The DropdownWidget takes care of opening and displaying the menu so that users can interact with it.
If you want to use this within an HTML form, such as a OO.ui.FormLayout, use OO.ui.DropdownInputWidget instead.
For more information, please see the OOUI documentation on MediaWiki.
Example
// A DropdownWidget with a menu that contains three options.
const dropdown = new OO.ui.DropdownWidget( {
label: 'Dropdown menu: Select a menu option',
menu: {
items: [
new OO.ui.MenuOptionWidget( {
data: 'a',
label: 'First'
} ),
new OO.ui.MenuOptionWidget( {
data: 'b',
label: 'Second'
} ),
new OO.ui.MenuOptionWidget( {
data: 'c',
label: 'Third'
} )
]
}
} );
$( document.body ).append( dropdown.$element );
dropdown.getMenu().selectItemByData( 'b' );
dropdown.getMenu().findSelectedItem().getData(); // Returns 'b'.

Properties
icon
#
The symbolic name of the icon (e.g., ‘remove’ or ‘menu’), or a map of symbolic names. A map
is used for i18n purposes and contains a default
icon name and additional names keyed by
language code. The default
name is used when no icon is keyed by the user's language.
Example of an i18n map:
{ default: 'bold-a', en: 'bold-b', de: 'bold-f' }
Note: the static property will be overridden if the #icon configuration is used.

simulateLabelClick()
#
Simulate the behavior of clicking on a label (a HTML <label>

override this method to provide intuitive, accessible behavior.
By default, this does nothing. OO.ui.mixin.TabIndexedElement overrides it for focusable widgets. Individual widgets may override it too.
This method is called by OO.ui.LabelWidget and OO.ui.FieldLayout. It should not be called directly.

element) bound to this input.
