Hello world,
Recently made Admin area to be ajaxfied too.
90% of links are ajaxfied
80% of forms are ajaxfied.
So finally admin area works as SPA too
It is very easy code, lucky SpaCart framework is easy to support admin area same as customer area.
So I was basically used same functions with jQuery. Forms are almost all submitted with Ajax now too.
All the best to you,
Oleg
