If you select a Collection to sync, all it's content will be synced. Thus no sub-selections can be made. So you're fine setting the sync selection in MMW as you're doing.

Wifi Sync on the other needs to be started from MMA.

I've just splashed out for MM Gold. I know all that's gone and I upgrade The reasoning being I want to run it so I can sync via wi-fi. Hoping that will be a) quicker and b) easier for me.
Anyway I have put my licence in and my Phone shows up in the tree as Phone (1) and Card. I wait till it's finished populating..again. I did have it so it wouldn't populate but my horrible memory has forgotten how I did it. So my music is on my E drive. I then go to Tools>Options>Portable Device Sync>Galaxy A10 Card>
Configure>Auto-Sync - Device. Then it has collections in the left hand pane and which files to keep synced in the right. How ever if I tick Music in the left hand pane the right greys out. If I try and tick the boxes in the right had the arrow to the left vanish and the box doesn't tick at all.

How does one start it in wi-fi sync mode please.

Where am I going wrong. It synced the other week, though it was a huge mess. But now I retagged all the Album Artists. It should sync perfectly. Should.
