I have created a HTML form designed with external CSS, images and JS file, now I need to add this HTML page into existing Joomla as Item page. How do I do that? It should show me the same header and footer of Joomla layout only the content should be my HTML form which contains scripts for ajax request and front-end validation, what is the best way to do that?
I know this is very late to answer this question. Even i face the same scenario and fixed it by adding iframe into the page.
<iframe src="form/html/url" frameborder="0"></iframe>
