Facelets template in another template

I would like to use the Facelets template in another template. I currently have a basic template, which so far has been sufficient for all the pages I have made. It has a top and a content area.

At the top there is a logo, menu, input / output functions, and the content area shows, well, the content.

Now I need to make another page (to save user profile information), where I would like to have a menu on the left and show the result to the right. This page should be inserted into the content area of ​​the base template.

Is it possible to create a new template that defines these two areas (profile_left and profile_content) and somehow use the basic template?

I see no reason why I couldn’t just copy the code into the base template and add the new “defines” that I want (profile_left and profile_content), but I'm still wondering if I can continue to use the original base template.

You can extend from the templates as deep as you want. It’s not true that you can only apply to one template or something that you think.

For instance:

/WEB-INF/templates/base.xhtml

 <!DOCTYPE html> <html lang="en" xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" > <h:head> <title><ui:insert name="title">Default title</ui:insert></title> </h:head> <h:body> <div id="header">Header</div> <div id="menu">Menu</div> <div id="content"><ui:insert name="content">Default content</ui:insert></div> <div id="footer">Footer</div> </h:body> </html>

/WEB-INF/templates/profile.xhtml

 <ui:composition template="/WEB-INF/templates/base.xhtml" xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" > <ui:define name="content"> <div id="profile_left"><ui:insert name="profile_left" /></div> <div id="profile_right"><ui:insert name="profile_right" /></div> </ui:define> </ui:composition>

/user.xhtml

 <ui:composition template="/WEB-INF/templates/profile.xhtml" xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" > <ui:define name="title">User profile</ui:define> <ui:define name="profile_left"> Profile left. </ui:define> <ui:define name="profile_right"> Profile right. </ui:define> </ui:composition>
