Is it possible to retain form radio selections using the back button?
Question
The user can select a radio button and depending on which radio button is selected, an input field can show asking for additional information. The user submits the form; then say they need to go back and make a change to the form. When they go back, the input field is no longer showing but the correct radio button is selected.
The answer only needs to work in IE8+. Using jQuery as part of the solution is also an option.

Use something like Sisyphus, gmail-like client side localStorage plugin. Probably your best option...

Your solution in JQuery:
Make an input type button
Put your expanded onclick options in a div with a class name someexpandedoptions
On the click event toggle visibility
$('.someexpandedoptions').css('display','inline');
$('.someexpandedoptions').css('display','none');
It's as easy as that.
Just make sure to properly initialize your buttons.
