I don't think it is possible to implement with the text/html module.
We had a similar discussion here:
http://www.dnncreative.com/Forum/ta...fault.aspxThe options are probably:
1) Create a custom module which incorporates the form elements that you need
2) Create a html page which incorporates the form and link to the html page from a page within your DNN portal. - style it to look like any other page within your DNN portal.
3) Create a html page which only contains the form that you require. FTP it to your DNN site. Within your DNN portal, create a new page and insert the iFrame module. - Set the iFrame module to the URL for the html page that you have just uploaded. - This will display the html page within a page on your DNN site. (You will need to check that the iFrame works within various browsers)
no. 3 will probably be the easiest and quickest to set up, but you will have to check for browser compatibility.
