Menus

Menus display a list of choices on temporary surfaces.

Usage

A menu displays a list of choices on a temporary surface. They appear when users interact with a button, action, or other control.

Principles

Nimble

Menus should be easy to open, close, and interact with.

Contextual

Menu content should be suited to user needs.

Scannable

Menu items should be easy to scan.

Types

Menus allow users make a selection from multiple options. They are less prominent and take up less space than selection controls, such as a set of radio buttons.

Dropdown menus display a list of options, triggered by an icon, button, or action. Their placement varies based on the element that opens them.

Exposed dropdown menus

Exposed dropdown menus display the currently selected menu item above the list of options. Some variations can accept user-entered input.

Elevation

Menus appear in front of all other permanent UI elements.

Menus appear at a higher elevation than all other permanent UI elements.

Height

The maximum height of a menu should be at least one row less than the height of the app’s UI.

The rows in this menu are 32dp tall. That’s also the space used between the menu and the bottom of the screen.

Position

Menus should be positioned relative to the edge of the screen or browser. They typically appear next to (or in front of) the element that generates them. If they are in a position to be cut off by the browser or screen’s edge, the menu can instead appear to the left, right, or above the element that generates it.

Menus can change their position to avoid being truncated by the screen or browser’s edge.

Anatomy

Menus display lists of related options (which can be grouped together) as well as unrelated options. Menus appear when a user taps an interactive UI element such as an icon, button, action, or content, such as selected items or text.

Actions

Disabled actions

Display actions as disabled when they can only be used sometimes, under certain conditions. They should be displayed as disabled rather than removing them.

The Redo action is disabled when that action isn’t available, and the Cut and Copy actions are disabled until content is selected.

Behavior

Scrolling

If not all menu items are displayed at once, menus can be scrollable. In this state, menus show a persistent scrollbar.

When its content is scrollable, menus display scrollbars.

Motion

Menus open using a scale animation (an animation that shows an element grow in size). The animation creates a relationship between the menu and the action that generates the menu.

Position

A menu’s position on screen affects where and how it will appear. If opened at the top of the screen, it will expand downwards (to avoid being cropped).

Menus at different positions on screen open in different ways, adapting to the space available.

By default, menus open with an entrance animation. However, on desktop, menus can skip the animation and open instantly instead.

1. Mobile menus have entrance animations. 2. Desktop menus have the option to open instantly

Usage

A dropdown menu is a compact way of displaying multiple choices. It appears upon interaction with an element (such as an icon or button) or when users perform a specific action.

Placement

Dropdown menus are positioned relative to both the element that generates them and the edges of the screen or browser. They can appear in front of, beside, above, or below the element that generates them.

Default placement

A dropdown menu is typically positioned below the element that generates it.

Cascading menu (Desktop only)

Cascading menus allow users to choose from a large variety of choices, by displaying menus with multiple levels of hierarchy.

They are organized into menus of parent list items that contain child list items. Child list items appear to right or left of parent list items, depending on where there is room to expand child list items.

A parent list item can trigger a cascading menus containing child actions.

Contextual menu

Contextual menus aren’t triggered by a consistent UI element. They appear next to where a user taps, and their actions can vary based on the tap target.

To reveal a contextual menu, tap and hold, or right click (desktop), selected text.
A contextual menu appears next to selected text.

Behavior

When an option is chosen from a dropdown menu, the element that generates it remains the same.

1. Tapping the icon triggers a dropdown menu 2. Choosing a menu option doesn’t change the icon of the element generating the menu.
