Hide html from when checkbox is checked via php

In my project I have a HTML page, some part of HTML file should display when a checkbox is checked, I used a Form tag cause I should submit that parameters to the server.
Here is that part of HTML file : ( The HTML file name is config.html)

   


    

        Subnet Mask
        

        
    

I did that in HTML file.
I include this HTML file in my Php file : ( My Php file name is configwireless.php )

I tried different ways to do this, But no chance.
Could anybody tell me what is the correct way by a simple sample?
Any help will appreciate.
thanks to all.
