问题 hope that title makes sense. I'm a noob at javascript. What I want to do is have a form which will have a couple of inputs like, name and url for example.

问题 I am building a drupal form with multiple ajax enabled form elements. I have one select list that does an ajax callback after change. The problem is that it adds a new select list to the page, which is also ajax enabled.
