 This is a simple input checkbox, radio and switch design.
 Please have a look at proper usage and recommendations: https://material.io/components/checkboxes
 
+Note: All generic attributes on the component, except `class` and `style`, are passed to the inner `input` element *(for the button type the attributes are passed to the `button` element)*.
