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 icon of the block (left most area in the toolbar) and click Columns / Container.

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 Style tab in the inspector where you will see the General panel. Open it and adjust the number of columns accordingly through the range control or by directly typing it in the Columns field.

In this example, we are adding 2 more extra columns to our Card block.
