Checkbox

Checkboxes allow users to select one or more items from a set. Checkboxes can turn an option on or off.

There's one type of checkbox in Material. Use this selection control when the user needs to select one or more options from a list.

Accessibility

Link to “Accessibility”

Add an aria-label attribute to checkboxes without labels or checkboxes whose labels need to be more descriptive.

<md-checkbox aria-label="Select all checkboxes"></md-checkbox>

<label>
  <md-checkbox aria-label="Agree to terms and conditions"></md-checkbox>

bookmark
checkboxes are not automatically labelled by <label> elements and always need an aria-label. See b/294081528.
