How to Add Columns to Blocks
To add columns to your blocks, you will need to transform the block itself into a column.
To do this, click the block and navigate to the toolbar. Select the block icon (left most side in the toolbar) and click Columns.
Note: Doing this is the same as adding a Column block with one column and moving your column block inside.
Alternatively, you can add a Column block and add your blocks inside.
Once you’ve transformed the block into a column, navigate to the Layout tab in the inspector where you will see the Layout panel. Open it and increase the number of columns through the range slider or by directly typing the number into the Columns field.
In this example, we are adding 3 more extra columns to our Card block.
