toggle - Best choice for three-state value?

In my application, the user can filter fields by selecting one of three possible values for each field:

• True


• False


• Both

I currently have a drop-down box, but this requires two clicks while the options are simple and should preferably being able to be selected by one click.

I faced the tri-state checkbox which shows either a tick, a square or nothing. However, this still sometimes requires two clicks to get from empty to square if the order is empty - tick - square.

Could someone please recommend what would be the best choice in this scenario?

Answer

Radio buttons. This is the exact situation that they are designed for.
