Change jinja template dynamically according to user input

I want to do something like

var radioId = $("input[name=id-radio-group]:checked", "#my-form").val();
document.getElementById("my-panels").innerHTML = ``;
document.getElementById("my-panels-2").innerHTML = ``;    

in jQuery script.

I know that I can never pass js variables to jinja template, since there are quite a lot of answers in StackOverFlow telling me that. But none of the "work-around" solutions those answers propose work for me.

So the question is, how can I use the radio selected by user in jinja template to produce panels specific to the option they chose?

FYI, I use python and protocol buffer.
