How to hide an object in the viewport but still be selectable? Thought the answer for this was straightforward, but that approach isn't working. 

For the Doorway.013 object you can see that 'Show in Viewports' has been unchecked, but 'Selectable' is still checked. However I can't actually select the object and move it, etc. Is there another toggle somewhere to make it work?

This appears to replace the 'transparency' option in previous versions of blender.
