Thank you for your question on having columns in your footer. By default, the footers are a single column wide. This means if you add more than one widget, they will stack on top of each other. There is, however, a way for you to have them side by side.
From the Customizer Menu, click on the ‘Advanced’ tab and then the ‘Footer Settings’ tab. From there, you will see a section for ‘Footer Widget Columns’. Select 3 and then click on the ‘Continue to Widgets Section’ button. Now you will see a tab for ‘Footer Center’ which will span then entire page width, and a tab for each footer column. The columns will be side by side so you should get the look you are after.
