Add optional disable prop to ToggleGroup component.

[indraraj]

Describe the issue. What is the expected and unexpected behaviour?
There is no way to disable <ToggleGroup> as a whole. There should be a prop like disable for ToggleGroup to do it.

Is this a bug or enhancement? If this issue is a bug, is this issue blocking you or is there a work-around?
Enhancement
Currently to disable the ToggleGroup I had to disable the ToggleGroupItem individually.
e.g
https://codesandbox.io/s/hy5kv?file=/index.js

Will transfer to design for further discussion.

[mcarrano]

@tlabaj I'm OK with supporting this. Do you see any downside? If not I will transfer back to React and get on our roadmap.

[mcarrano]

Will add this to our roadmap. Currently scheduling into Q1 2022.

[tlabaj]

@mcarrano I do not see a downside.
@mcoker, could we add a modifier to do this? Or will we have to disable each item independently in the react component?

[mcoker]

I think we'll want to disable the individual actions in the group for a11y purposes, so I think unless we want to apply specific styling when all actions are disabled, we could just do this by disabling each action.
