Hi troyhimes 

Thanks for your quick reply.  After testing, the source step itself is not collapsible, it only acts as a connector to connect to the data source, but in order to ensure that the later steps can be collapsed， you can refer to the following steps:

1.Make sure that your connect mode is import, don't filter in advanced options. just click ok

 

2.Select the database , then click 'Transform data'

 

3.Add a new step in power query , then refer to the following code.

 

= Value.NativeQuery(xxxx(your database name),"select * from SQLTest",null,[EnableFolding=true])

 

Then you can find the query folding can use.

And you can refer to the following video.
