gmailgmail-labels
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?
Search for string before:date (date in format yyyy-mm-dd) and then choose More > Mark all as read.
Watch out: This will select also emails from this date! I.e. before:2012-07-12 will select email received before 12 July 2012, but also emails received on 12 July 2012.
There is a step-by-step solution here, and it works:

Mark as read."
Best Answer
select the label, in the search bar, it will show
label:mylabel- addlabel:unreadand search.select all messages by ticking the top left checkbox
if there are more unread messages than can be displayed, a small notice will appear above the first message in the search results - you want to select all messages which match the search.
now you can click the 'more' button and select the 'mark as read' option.
