Templates

Templates define the structure of the Page; without template we cannot create any Page. 

Template defines the Where the Iparsys and Parsys have to be added and what components should be displayed on the layout container.

Prior AEM 6.2, there were only static templates, from aem 6.3 Adobe introduced Editable Templates/Dynamic Templates.

1) Static Templates

Static Templates are created by the Developer, where content author just uses the templates and creates the Pages.  If you want to enable any components to be shown on the page then on the page needs to go to design mode and add the specific components.

In static templates by default some component needs to shown on the Page then developer needs to add the component on the template through code.

Editable Templates

From 6.3, Adobe introduced new feature of Editable templates.  The content author can create templates and can add structure, initial content, Policies. 

Editable Template contains mainly 3 features

1)      Structure : This defines the structure of the page and components included on the parsys/iparsys. Also you can add specific components on the Template, and you can restrict the author to edit the added components by lock/unlock feature on the component.

2)      Initial Content:  By default, when the page is created then what ever you add in the initial content that will be automatically added to the Page.

3)      Layout/Emulator: This defines the view of Mobile, Desktop, Tablet.

   Policies:

Policies are of 2 Types.

• Template level Policies
• Component Level Policies

If you want to add any new component, to be shown on the author mode then the component should be added to the template level Policies.

If you want to add any Styles to the specific component then that should be on the component level Policies.

***All the Policies are stored under /conf/project-name/settings/wcm
