Facebook application / embeded page

I need to make a Facebook application . I need to embed this page ( re-designed to fit facebook ) into a tab on the FB group. Example : [login to view URL] I dont want to embed the full page . I want to embed the MEnu/Info part and below - until the end of the menu. Furthermore , I want it to talk to my website [login to view URL] though API Send and receive data .... through API Please not the register button and login button on [login to view URL] ( at the top right of the page ) This should be considered in your work . In all cases , the final product is going to be a tab that is available on the FB group with the title" Order Online " When a customer clicks on this tab , they will get the menu and they can place their orders directly from the FB page , after that happens , the order will talk to our system through APIs Please let me know if you have any questions
