Checkbox

This documentation is fully rendered on the Material Web catalog.

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.

Usage

Checkboxes may be standalone, pre-checked, or indeterminate.

<md-checkbox touch-target="wrapper"></md-checkbox>
<md-checkbox touch-target="wrapper" checked></md-checkbox>
<md-checkbox touch-target="wrapper" indeterminate></md-checkbox>

Label

Associate a label with a checkbox using the <label> element.

<label>
  <md-checkbox touch-target="wrapper"></md-checkbox>
  Checkbox one
</label>

<md-checkbox id="checkbox-two" touch-target="wrapper"></md-checkbox>
<label for="checkbox-two">Checkbox two</label>

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>
  Agree
</label>

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

Theming

Checkbox supports Material theming and can be customized in terms of color and shape.
