<translate> Template style is a feature introduced in that allows users to assign different template styles to individual menu items. By default, Joomla! assigns a template style to all menu items upon installation. A yellow star indicates the default template style in use. A default template style can be partially or completely overridden by assigning different template styles to the desired menu items in order to obtain a different look for their respective pages.
A template style can be assigned to menu items one of two ways.
Go to Menus > Menu Name, choose a menu item by checking the box to the left of its name and then click on the Edit button. Alternatively, simply click the name of the menu item to edit it.
On the Edit Menu Item screen, in Template Style, choose the desired template style and click on the Save button.
Go to the fronted of your website and refresh the page to view the modifications.
