title: Is it possible to set global variables in a Zeppelin Notebook?
body: <p>I'm trying to create a multi-paragraph dashboard using a Zeppelin notebook. I'd like people using the dashboard to only have to enter certain parameters once. E.g. if I'm making a dashboard with information about different websites, the dashboard user only has to select the particular website they want information about once and the whole multi-paragraph dashboard will update. Is this possible? How do I set global variables like this in a notebook?</p>
  
  <p>To clarify, the parameter input that I intend to use for Zeppelin is referred to as <a href="https://zeppelin.apache.org/docs/latest/manual/dynamicform.html" rel="noreferrer">"dynamic form"</a>.</p>
