title: WPF input method for a 'tag list'
body: <p>I'm looking for WPF component (if it exists) to input tags in a similar fashion to what StackOverflow.com provides when inputting tags for a question.</p>
  
  <p><img src="https://i.stack.imgur.com/gZZJC.png" alt="Tag input"></p>
  
  <p>Does such a component exist? If not, what would be the best approach? I was thinking about a textbox with a certain padding to reflect the position of existing tags, but it seems like a lot of work since it most likely requires custom measure/arrange implementations.</p>
