I have a new interaction on a couple pages where I let the user collapse/expand a side panel. I'd like to save state, so that when the page is loaded subsequently, I can show each panel in its previous state.\
After reading around, it seems that since javascript cant set server- side session variables, the 2 approaches mentioned are to set a cookie or to go with ajax.
Not sure how I feel yet about the cookie approach, but a round trip back to the server for a client-side interaction doesnt seem like the best approach.
Do others feel the same way or am I missing something here?
Are there other approaches suggested?
