title: select2 - hiding the search box
body: <p>For my more significant selects, the search box in Select2 is wonderful. However, in one instance, I have a simple selection of 4 hard-coded choices. In this case, the search box is superfluous and looks a little silly being present. Is it possible to hide it somehow? I took a look through the documentation online and couldn't find any options for this in the constructor.</p>
  <p>I could, of course, just use a regular HTML select, but for consistency, I'd like to use Select2 if possible.</p>
