title: HTML Form text input suggestions box
body: <p>I am attempting to modify one of my text input boxes in a form that I have. I would like suggestions to pop up as the user types. Basically, I would like to emulate the "Tags" box that is on the ask question pages here on Stack Overflow, but with different data as the suggestions obviously. How would I go about doing this?</p>
  
  <p>For context, this is for a club at a college, and I am trying to allow members to type in their majors and as they type have a suggestions come up.</p>
