  <p>This is my init:</p>
  
  <pre><code> &lt;!-- TinyMCE --&gt;
          &lt;script type="text/javascript" src="js/jscripts/tiny_mce/tiny_mce.js"&gt;&lt;/script&gt;
          &lt;script type="text/javascript"&gt;
              tinyMCE.init({
                  mode : "exact",
                  elements : "pagina_testo_colonna1,pagina_testo_colonna2,pagina_testo_colonna3",
                  theme : "advanced",
                  plugins:"paste,autoresize",
                  plugin_preview_width : "100%",
                  width : "100%",
                  theme_advanced_buttons1 : "pastetext,|,bold,italic,underline,strikethrough,|,bullist,numlist,|,indent,outdent,|,undo,redo,|,justifyleft,justifycenter,justifyright,justifyfull,|,link,unlink,|,charmap",
                  theme_advanced_buttons2 : "",
                  theme_advanced_buttons3 :"",
                  theme_advanced_disable : "image,anchor,cleanup,help,code,hr,removeformat,sub,sup",
                  theme_advanced_resizing : true,
                  paste_text_use_dialog : true,
                  relative_urls : false,
                  remove_script_host : false
  
              });
          &lt;/script&gt;
          &lt;!-- /TinyMCE --&gt;
  </code></pre>
  
  <p>i have added "autoresize" to plugins list but my editors not resize while i writing, they simply scroll. I have multiple editor in the same page. What's wrong with my code?</p>
