For example I have UI Accordion with multiple section like 1. Order Details +

SAVE / NEXT - button

2. Supplier Details + 

[by default not visible]

3. Item Details +

[by default not visible] now in this above example when user click on SAVE / NEXT button then only 2. Supplier Details should open and expand like wise all the section open base on button click by default only 1. Order details section should open. I mean client control we have to handle from server side events. I hope it is more clear for you.
