title: Use JQuery(?) to add multiple values to list to return with 1 postback
body: <p>I'm having a conceptual problem. I have this asp.net page to manage code snippets. Now I would like to add tags to this snippet before submitting it. Something like you can do with stackoverflow. I'm wondering how I should go about to do this?</p>
  
  <p>I thought about a hiddentextbox, which is filled in by jquery when a user selects a value from a dropdown list, seperated by ";", which could be read and seperated serverside. But this is vulnerable to tinkering i guess?</p>
  
  <p>Is there any proper way to do this?</p>
