Django: Change page when drop down menü value is selected

I am trying to change the variables used to display a page with a selection-box when another value of the selection box is chosen. I´ve got three different folders I want to apply settings to (with radio buttons). The folder can be chosen from the dropdown menü, and then the needed values can be chosen with the radio buttons. My problem is a follows: I want to display the previously selected settings by checking the options that where chosen before. So if I change the folder I want to apply settings to, I want the checked radio button to change accordingly. Therefore I would like to do something like this:

is that possible ?
