Can someone give me a hint on this?

Question

Hi everyone,

Hope all are fine here.

I have a requirement in my web application where i have 4 checkboxes [business address,shipto address,billto address,others]. And only 1 textbox for address[multiline].based on used selection a pop up window should be displayed which again should have textboxes for entering street1,street2,city,state,oincode,country. After user enters the data and clicks ok the data should appear in the address textbox[multilined]. How do i save the data if user enters more than 1 address in that page and later save in database?
