`paper-checkbox` is a button that can be either checked or unchecked. User
|
|
can tap the checkbox to check or uncheck it. Usually you use checkboxes
|
|
to allow user to select multiple options from a set. If you have a single
|
|
ON/OFF option, avoid using a single checkbox and use `paper-toggle-button`
|
|
instead.
|
|
|
|
Example:
|
|
|
|
<paper-checkbox>label</paper-checkbox>
|
|
|
|
<paper-checkbox checked> label</paper-checkbox>
|
|
|
|
