Hello  @peterfest,
Theme by default shows the content in the single column . However if you want to make them appear in two column then create columns  through use of  HTML and CSS. To create columns in the text editor use the 
 tag along with a style attribute.
You can also find many plugin for this. Below is the link to one of them.

Note: But we cannot assure 100% compatibility of the plugin with the theme as we  have not done any compatibility testing with the theme.
Hope this helps.
Best Regards!!
Have a good day.
