Templates
Templates are collections of "containers", each of which can be arranged in a different place on a page or have a different function. To select the correct template for your page, you'll want to know how many columns and rows your page has, whether or not it has a side navigation bar, and what types of capabilities you need (for example, do you need just a basic column or two of content or do you also want to feature entries in a row across the top?).
To switch a page's template in dotCMS, click on the "Page Properties" button for that page, and use the "Templates" drop down menu.
