Develop custom layout templates
You can add new layout templates so that they can be assigned to portal pages.
Layout templates are stored in the WebDAV filestore at the location /fs-type1/layout-templates. To add a new layout template so that it can be assigned to portal pages, create a new folder or copy and rename an existing layout template folder inside the root folder. Include all CSS files in the theme that are used by the new layout template.
If you implement a complex layout template that requires its own JavaScript handling, ensure that the required JavaScript components are loaded and initialized by the theme. For best performance, build and minify all JavaScript used into a single, cachable file that can be loaded once and cached by the browser.
For details about the syntax and elements of layout templates refer to the topic about Theme layout templates.
