Blocks are items (menus or informational) which can be added to the left column in your Moodle course. The most common blocks used are the Calendar, Navigation, Administration, and Course Menu.
Blocks can also be “docked” off to the left side and out of sight.
From within your course in Moodle, Turn editing on, look for the Add a Block menu block at the bottom of the left column. Click the drop down arrow next to Add…
Click on the block you want to add. Note: If a block is “missing” from the list, check your course, it may already be there. The screen refreshes and the block is added to the column.
With editing turned on in your course, locate the Move icon in the upper right of the block (just below the block title). The icon looks like multi-directional arrows.
With your mouse pointer over the Move icon, click and hold, and then drag and drop the block to where you would like it placed.
With editing turned on you will also see the settings gear icon in the upper right of your blocks.
Click on it and then select what you would like to do with the block:
You can Dock blocks off to the upper left corner of the screen. When a block is docked, just mouse over it and it will expand the menu.
To dock a menu, click the Dock icon located in the upper right corner of the block (square with a less than symbol in it).
To undock a menu, hover over the menu in the docking bar, click the Undock icon located in the upper right corner of the block (square with a greater than symbol in it).
You can Hide, or collapse, a block so all you see is the block title by clicking on the Hide icon (square with a dash in it) in the upper right corner of a block.
To Show the full block again, click on the Show icon (square with plus sign in it) in the upper right corner of the block.
