Inspired by Amaz0n account address book page, I decided to give it a try with my ZC store account address book. It worked out grate. This is a much more clean updated page and changing default address is a one click event. I also redid all my account pages, but this was the most requested part.
All addresses are contained in fieldsets with links to edit, delete and make primary within each container. The add address container with just the add button lets the user know they have space for more. Once all addresses are full, the add box is not displayed.
Containers stack when the screen width changes making it responsive all on its own. No need for additional css or scripting.
You can download the full package with instructions from our store free download page.
