Option select example
  
  
With aria controls
aria_controls_id adds an aria-controls attribute to each checkbox input. This makes it easier for users of assitive tech to jump from them to the part of the page they’re updating.
The aria_controls_id must be set to the ID of an element that’s on the page or it won’t be included.
