This idea is a wordpress plugin, that link to a wordpress menu, and then display the the demo website menu based on that menu.
– Choose demo folder in user’s website, such as webfacescript.com/demo
– Add user’s logo
– Use the menu link as demo menu link
– Put post/page ID to menu link, then demo plugin will auto get the demo link from custom field (is defined by user) from the post/page
– Smart demo by parameter demo_link
– Multi demo styles for changing
