     Can Select2 be used with a <code>&lt;select&gt;</code> tag?
   </h2>
 
+  <p>
+    Select2 was designed to be a replacement for the standard <code>&lt;select&gt;</code> boxes that are displayed by the browser, so by default it supports all options and operations that are available in a standard select box, but with added flexibility. There is no special configuration required to make Select2 work with a <code>&lt;select&gt;</code> tag.
