Add 'check' option in @storybook/addon-ondevice-controls

[simonadenic]

Is your feature request related to a problem? Please describe.
I have a need for a property to choose on/off from multiple options. Example: component has fontWeight property, which can be 'bold' or undefined. I need to have a selection between those two. This could only be properly represented by checking the 'bold' or unchecking it (as a value).

Describe the solution you'd like
I would like type:'check' in controls addon, just like on the web

Describe alternatives you've considered
I've considered using some of the options available such as 'select', but none of these match my use-case.

Are you able to assist bring the feature to reality?
No

@simonadenic we have the boolean type, maybe that can work? However we can definitely add the check control type

I tried the boolean type, but it doesn't correspond to my needs (since fontWeight true or false would need to be mapped to fontWeight='bold' or fontWeight=undefined in the component render). The type of my property is fontWeight?: 'bold'. Its defined like this to support future fontWeights planned (fontWeight?: 'bold' | 'bolder' | 'boldest' or something similar).

Anyhow, it seems that every optional property in the component would require the check type, rather than select, radio or any other :)

what you can do is map the type to the appropriate value by having a render function, though I understand that it would be better to add the control type. I will do that soon after v7 probably

So I've implemented something for this but I don't really know if it does what you want, it returns an array of the selected options, how would that work for your case?

please check #553 if you want to see the implementation, it's basically a copy of the web component
