Full Width Template

Hello,

I tried selecting Full Width with no sidebar from templates on a page or article, but can't find that option. Only the default one that has a sidebar for widgets and the Contact form one.
I really need to use a template with no sidebar for one of the pages. Because it does not show up properly with the right sidebar.
Please let me know on how can I add a full width template.

Thank you.

I found out how to change it from Content Layout.
