Populating drop down list with SharePoint Managed Metadata

[haniel]

Hi,

Is there a simple way to populate a drop down list in PowerApps with values from a SharePoint term set from managed metadata?  If so, what should be the Data setting for the drop down?  In my example, I tried to bind the drop down to a list column, where Metadata List is the name of my list and Source is the the metadata.  Not sure if that could work.

I have seen @paul_culmsee's series on this topic (http://www.cleverworkarounds.com/2017/10/14/powerapps-flow-and-managed-metadata-fields-part-1) , but am wondering if there's a simpler work-around. 

Thanks,

-Haniel

That is an old article. Now there is the Choices() function. Check out this video for how I used it...

Paul love your solution but it returns max 20 terms.  Any idea how to have it return the entire TermSet?

Yes thank you.  I was looking at that before.  Works great but had to brute force parsing the path using multiple forall() and collections.  I have a 4 level deep term set.  So I first split() the path and stored results in a new collection.  Then went through multiple forall() and clearcollect() iterations to get the first() or last() of the path in a column and then used another forall() with Len() and Mid() to get the middle paths.  It took me 3 loops and collections to properly break down a 4 level deep term set.  

Would love to know if there is a more elegant way to grab the path levels from the table after the split function.
