Hey Rui,
Yes, I wanted to create a new footer layout as shown here:
https://www.dropbox.com/s/vgm2fpg8gfa3w20/Screenshot%202015-02-03%2016.20.19.png?dl=0
which is col-sm-6, col-sm-2, col-sm-2, col-sm-2
Now, I have created this by modifying the core sf-footer.php file (changing footer-2), which we prefer NOT to do for upgrade compatibility reasons.
Therefore, I want to accomplish two things so that I can create additional layouts and select them at will:
1) Modify the core files in the child-theme only, if possible
2) Add new layout(s) (footer-9, footer-10, footer-11, etc) and have them available for selection in the Cardinal Theme Footer Options tab.
So, I guess I need to know what other core files must be changed to accommodate my request.
Thanks!
Steve
