Class: DropdownWidget

.ui.DropdownWidget(configopt)

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.
Parameters:
Name Type Attributes Description
config Object <optional>
Configuration options
Properties
Name Type Attributes Description
menu Object <optional>
Configuration options to pass to menu select widget
$overlay jQuery <optional>
Render the menu into a separate layer. This configuration is useful in cases where the expanded menu is larger than its containing `
`. The specified overlay layer is usually on top of the containing `
` and has a larger area. By default, the menu uses relative positioning. See .
