Button Groups join two or more buttons into a unified control, formerly called a segmented control.

Guidelines

Use When

  • Toggling through content in an adjacent container.
  • Switching units, currency, or increments.

Visual Language

  • Never allow button groups to wrap, instead, consider using a single Button that triggers a Menu of options.

Behaviors

  • By default, the button group should start with its first item in the active state.

Editorial

  • This component looks best when the content is balanced.
  • Ideally, button labels should have the same number of words. Preferably one word each.
  • When impossible, button labels should be within one word of each other, count wise.
    • Do: Files / Forms & Reports
    • Don't: Files / Market Commentary for Advisors / Reports
  • See Buttons for more guidance.

Accessibility

  • Include a role="group" attribute for a default button group.
    • If a button group is used for navigation, set role="navigation".
    • If a button group is being used as a toolbar, set role="toolbar".
  • Include an aria-label="..." to describe the intention of the button group.
    • For example, aria-label="View Toggle" could describe a button group set that changes the view of a content module below the button group.
  • See Buttons for more guidance.

 Outcome

mds-button-group

<div>

Adding an mds-button-group wrapper to a group of mds-buttons initializes the button group component and adjusts the spacing between the buttons to conform into one conjoined group.

mds-button-group--justify

mds-button-group

Adding this modifier to the mds-button-group will set the component to fill the full width of its container. The individual mds-buttons within the group will all receive the same widths, and be evenly dispersed across the wrapping container.

mds-button-group--icon-only

mds-button-group

Adding this modifier to the mds-button-group will apply overrides for icon-only buttons.

mds-button-group--flex

mds-button-group

Deprecated, will be removed in v3.0. Adding this modifier keeps all of the buttons the same height even when one of the buttons has wrapping text. Only use when text wrapping occurs within the button group.
