A Select is an input with a dropdown menu of predefined, selectable items.


Using selects

Selects must feature a label stating the current selection and a menu of at least two, but preferably three or more, options.

Use the Select component when users need to choose an option from a predefined list. For example, to select a country or category. If the list of options is too long, consider using Combobox instead. If users need a multi-selection, use a Checkbox group instead.

Example of a Codex Select with the menu displayed.


Specification of Select.

  1. Icon (optional)
    An icon can simplify the identification of the available options in selects.
  2. Label
    Dropdown labels communicate what selections the component conveys. Labels are required for selects.
  3. Arrow indicator
    Selects have a button-like appearance, and include a mandatory arrow indicator to communicate that they can be expanded.
  4. Menu
    When the select is open, a menu with options is displayed.

Refer to the Select component in Codex Figma.

Interaction states

Selects have the following visually separate states:

States of the Select component: default, hover, focus, error, disabled, active, and filled with one option selected from the dropdown menu.

  1. Default
  2. Hover
  3. Focus
  4. Error
  5. Disabled
  6. Active select with menu displayed
  7. Active select and hover on one of the menu options
  8. Active select and one of the menu options being pressed
  9. Active select with one of the menu options selected
  10. Filled (with one option from the menu selected)

Accessibility note

The disabled state does not meet our minimum color contrast rules. WCAG 2.1 states that “…part[s] of an inactive user interface component […] have no contrast requirement”. [1]
Provide sufficient information in a disabled element's context, so the user can understand what is disabled and how to enable it (if applicable).

Note: For icon properties, the relevant icon also needs to be imported from the @wikimedia/codex-icons package. See the usage documentation for more information.

Basic Usage

Menu items must have a value, and can have a label to display in the UI. If no label is provided (like the third menu item in this example), the value will be displayed.

With menu item icons and descriptions

Items are displayed via the MenuItem component—see the MenuItem docs for more options. In this example, a menuConfig object is passed to the Select to bold the label text and hide the text overflow of the descriptions.

With custom menu item display

The menu-item scoped slot enables you to customize the display of each menu item, with a binding for the menuItem. In this example, only the menu item's icon is displayed in the menu.

With custom label display

The label scoped slot enables you to customize the display of the label, with bindings for the selectedMenuItem and the defaultLabel.

With configurable scroll

By default, all menu items are displayed when the menu is expanded. To limit the height of the menu and enable scrolling, use the visibleItemLimit property of the menuConfig prop.

Form field

A Select can be wrapped in the Field component to add features like a semantic label, description and help text, validation messages, and more. See the Field page for more information.

Special:Search is better for searching text-based items like articles. Special:MediaSearch provides a better interface for searching files.

Vue usage

Menu items are provided as an array of MenuItemData types, and v-model is used to bind the current selection's value.


Prop nameDescriptionTypeDefault
menuItems(required)Menu items. See the MenuItemData type.MenuItemData[]
selected(required)Value of the current selection.

Must be bound with v-model:selected.

The property should be initialized to null rather than using a falsy value.
defaultLabelLabel to display when no selection has been made.string''
disabledWhether the dropdown is disabled.booleanfalse
menuConfigConfiguration for various menu features. All properties default to false.

See the MenuConfig type.

CSS-only version

Markup structure

The CSS-only version of this component uses the native <select> element. This element will be styled to match the Vue version, but the menu will use native browser styles.


Add the disabled attribute to the <select> element to get a disabled element with appropriate styles.
