Re: How to multiSelect with selection manager in power bi custom visual

Thanks so much for your detailed response.  I had already tried a similar approach using

	var selectionId = SelectionId.createWithIds.apply(SelectionId, categoryIdentities);

I implemented your approach and it seems to work the same as my createWithId options.   However, I may be doing something dumb but this approach does yield an error it just generates the wrong results when multiple items are selected.

Perhaps, it is because I am trying to use apply to create the comma delimited list of parameters?  I am not really familar with using apply but I am using it because it was the only way I could figure out to dynamically pass a large number of parameters.

	var SQExpr = data.SQExprBuilder.or.apply(data, categoryIdentitiesExpr);
        var identityExpr  = data.createDataViewScopeIdentity(SQExpr);
        var selectionIdExpr = SelectionId.createWithId(identityExpr);

So i have now tried this 3 ways, 1) The default granular approach 2) aggregating with SelectionId.CreateWithIds and 3) aggregating with SQExprBuilder.

I have updated the public gist with the last approach at:  https://gist.github.com/jcbowyer/5df55d4758a7614ca08d71eaf640fc57

I think this could be a really valulable custom visualization for the community if I we could solve this.   If you have some spare time and want to discuss a small part day consulting engagement to help me through this, please pm me.  I would be very grateful and don't know where else to go for expert guidance/help.   Thanks again.
