Buttons

Buttons

Buttons communicate the action that will occur when the user touches them.

Material buttons trigger an ink reaction on press. They may display text, imagery, or both. Text buttons and Contained buttons are the most commonly used types.

Text Buttons

Text buttons are typically used for less-pronounced actions, including those located:

  • In dialogs
  • In cards

In cards, text buttons help maintain an emphasis on card content.

Outlined Buttons

Outlined buttons are medium-emphasis buttons. They contain actions that are important, but aren’t the primary action in an app.

Alternatives

Outlined buttons are also a lower emphasis alternative to contained buttons, or a higher emphasis alternative to text buttons.

Link

Contained Buttons

Contained buttons are high-emphasis, distinguished by their use of elevation and fill. They contain actions that are primary to your app.

Floating Action Buttons

A floating action button (FAB) performs the primary, or most common, action on a screen. It appears in front of all screen content, typically as a circular shape with an icon in its center. FABs come in three types: regular, mini, and extended.

Only use a FAB if it is the most suitable way to present a screen’s primary action.

Only one floating action button is recommended per screen to represent the most common action.

The floating action button animates onto the screen as an expanding piece of material, by default.

A floating action button that spans multiple lateral screens (such as tabbed screens) should briefly disappear, then reappear if its action changes.

The Zoom transition can be used to achieve this. Note that since both the exiting and entering animations are triggered at the same time, we use enterDelay to allow the outgoing Floating Action Button's animation to finish before the new one enters.

Sizes

Fancy larger or smaller buttons? Use the size or the mini property.

Icon Buttons

Icon buttons are commonly found in app bars and toolbars.

Icons are also appropriate for toggle buttons that allow a single choice to be selected or deselected, such as adding or removing a star to an item.

Buttons with icons and label

Sometimes you might want to have icons for certain button to enhance the UX of the application as we recognize logos more easily than plain text. For example, if you have a delete button you can label it with a dustbin icon.

Customized Buttons

If you have been reading the overrides documentation page but you are not confident jumping in, here are examples of how you can change the main color of a Button using classes, and using a theme; and of a Bootstrap style Button.

Complex Buttons

The Text Buttons, Contained Buttons, Floating Action Buttons and Icon Buttons are built on top of the same component: the ButtonBase. You can take advantage of this lower level component to build custom interactions.

Third-party routing library

One common use case is to use the button to trigger a navigation to a new page. The ButtonBase component provides a property to handle this use case: component. Given that a lot of our interactive components rely on ButtonBase, you should be able to take advantage of it everywhere:

import { Link } from 'react-router-dom'
import Button from '@material-ui/core/Button';

<Button component={Link} to="/open-collective">
  Link
</Button>

or if you want to avoid properties collisions:

import { Link } from 'react-router-dom'
import Button from '@material-ui/core/Button';

const MyLink = props => <Link to="/open-collective" {...props} />

<Button component={MyLink}>
  Link
</Button>

Note: Creating MyLink is necessary to prevent unexpected unmounting. You can read more about it here.
