Blocks: Mass Actions block
This block allows instructors to perform actions upon multiple resources or activities, rather than having to perform repeated actions on individual items.
Supported actions include mass selection, indentation, deletion, hiding, showing, and moving. To select items to perform actions on, simply click the checkbox to the right of it in the course home page or use select functionality, then click the action you would like to perform in the block.
Note: the original block for Moodle 1.9 is on http://tracker.moodle.org/browse/MDL-20213; this is the version for Moodle 2.
