Blasts allow you to add up to 4 Elements side by side on each row.
To add additional columns to your Blast, you can either drag and drop New Elements beside an existing element, or you can move an existing Element next to another existing Element.
Drag and Drop
If you want to add an Element next to an existing Element, click and drag the Element next to the existing Element. You will see a blue line appear next to the Element. When you see this line, you can release the Element to drop it into the Blast Editor.

Move an Existing Element
If you want to move an existing Element next to another Element to create a column, hover your cursor over the Element you want to move.
Click the first icon (two columns of dots) and drag the Element where you want it placed. You will see a blue line appear, and that is when you can release the Element to move it.
Please Note: You will not see the overlay actions if you are currently editing an Element. To see these actions, you will need to make sure you do not have any element currently selected - please keep or discard any edits you're currently making to an element.

Display of Elements on Mobile
When a Blast is viewed on a mobile device, it will only show as one Element wide. If there are multiple columns in your Blast, the Elements will stack vertically top to bottom, from left to right respectively. Pre-grouped Elements like 'Image + Text' will maintain their layout.
