State emitter for checkbox

Hi Filipe

Sorry for the late reply. I’m just coming off a little bit of a holiday :)

I haven’t actually tested state emitters with a checkbox, but I imagine you could do this with a simple conditional state emitter. Something along the lines of

'state_emitter' => array(
    'callback' => 'conditional',
    'args' => array(
        'group[active]: val',
        'group[inactive]: !val',
    )
),

And then you’ll just need to handle that with a state handler – https://siteorigin.com/docs/widgets-bundle/form-building/state-emitters/#heading-state-handlers

If the standard conditional state emitter doesn’t work for a checkbox, then you could also try a custom state emitter. This would give you fairly fine grained control over the state that’s emitted from the checkbox.

As soon as I get a chance I’ll take a proper look at checkboxes and state emitters. So far, in our own widgets, we’ve only ever needed them for select fields.
