How to mark all emails as read on a certain label with several sub labels

Question

How can I mark all emails as read on a certain label with several sub labels in Gmail? I have a label, say Projects, with several sub-projects, like ProjectA ProjectB, ProjectC underneath it.

Is there a simple way to mark all emails under Projects to be marked as Read?

Answer 1

With Google mail, go to the parent label ("Projects") and with each sub label it should appear to the left of the subject, with this screen (on the parent label) tick all and mark as read.
