Im new here...

I have problem, i am not a coder but im try to be one... he he

Here is the problem,

i use Joomla CMS, so i need to create one article in it that will look something like http://support.amd.com/us/gpudownload/Pages/index.aspx

As u see, when u click on your choice u get another and another and another till the end, but here, on the end u get download link and i will need contact form that a user make his selection and that selection will be sended with his contact informations via contact form to me.

I will have more selections that are here with drivers so i have thinking on dropdown menus in forms.

How to make that?
