body: <p>In rails, jQuery token input is not allowing custom entry.</p>
  
  <p>I have downloaded 1.6.0 version of token input but i can't enter custom entry. As soon as i enter some text in a text box &amp; take out cursor, the text will disappears.
  Only i need to select from auto completion list.</p>
  
  <p>Eg :- If i am using below kind of script function, what will be the solution ?</p>
  
  <pre><code>&lt;pre&gt;
  &lt;script type="text/javascript"&gt;
  tokenInput("SOME_ID", "/token_input/name");
  
  function tokenInput(text_box_id, url){
      jQuery("#" + text_box_id).tokenInput(url, {
        allowCustomEntry: true,
        preventDuplicates: true,
        theme: "facebook",
      });
    }
  &lt;/script&gt;
  &lt;/pre&gt;
  </code></pre>
  
  <p>Please give me the solution for this, token input should allow the custom entry.</p>
