Sites page into an experience fragment

Experience fragment (XF) is internally saved as a page. So, all the things that we can do on the page can be mirrored on the experience fragment. But, you might not be allowed to add forms component to it (As it may not be allowed by the template which XF is using). This is because the user who is creating the Experience fragment should not be having rights to configure the allowed components.

Refer this thread:-AEM 6.3 Experience Fragments for knowing how to create XF template.
