Airtable blocks are a Pro plan feature, letting you extend the functionality of your bases.
You can view your base's blocks in a split screen view or a full screen view. To switch between them, click the expand button in the top right corner of the blocks panel, or simply click to drag the dividing line left or right.
You can also expand an individual block to fill the whole screen by mousing over it and clicking the expand button.
To rearrange blocks, mouse over the block you wish to move and click and drag using the drag handle in the top right corner. To resize a block, click and drag from the bottom right corner.
To add a new dashboard, navigate to the blocks dashboard you're currently on. On the left of the dashboard, you'll see the name of your current dashboard. Click the down arrow to the right of the name, and select Add a dashboard.
To rename, duplicate, disable, move, or delete a block, click on the dropdown arrow next to the name of the block. You can also adjust the settings of the block in this menu.
