Async select with grouping and only 1 option per group

[cubecleveland]

Hi, I am getting great answers from this forum and here is yet another one:

We have a use case of Async select that will allow only 1 selection per group
Right now here is where we are..(
On a a promise return inside loadOption we reorganize the data to include grouping and return a well formatted group data.) how would we take it from here only allowing in the multi select to allow 1 option per group ?

I would approach it by using the optionIsDisabled prop and updating the list of selected group options when an onChange event occurs.
