Two possible + set indeterminate

[BenjaminHorn]

Is it possible to have a behavior like the standard checkbox?
While clicking it it only has two possible states (checked / unchecked) but it is possible to set it to indeterminate via javascript.
Something like:

just with the plugin's nice styling.

btw I tried to use the plugin in jsbin but it failed. I can see the changed markup (cbx-container etc.), but the new styling is not applied
