How to show a block next to the other?

In the region properties, configure the Distribution property to Horizontal or Vertical.
If the region is only going to have those two blocks, for the region configure Distribution -> Direction: Horizontal.
If there are going to be more blocks in the region and you want their direction to be vertical, create a group to place one block next to the other. Next, configure Direction: Horizontal for the Group.
