Moodle Blocks provide additional functionality and content to your module. Some blocks are added by default to all modules and other Blocks can only be used when an activity of that type is enabled on the module e.g. Attendance block or Course completion block.
Blocks display in the Block drawer on the right hand side of a module page. The ability to open the Block drawer is available to students even when they access Moodle on a mobile browser. Staff and students can choose to close the Block drawer when it is not required.
In Moodle 4, staff and students can also add Blocks to their Dashboard page.
To view blocks on your module:
Deleting a Text block deletes the content and the content cannot be reinstated.
