How to make inactive choice years in the calendar?

Hi all. Has anyone worked with this calendar docs.dhtmlx.com/calendar__index.html? All in it arranges, but there is one drawback. You cannot restrict the selection range of years in the pop-up tooltip. Maybe someone knows the solution to this problem? Or advise, pliz, another calendar with that option (without jquery, this is important).

In General solved a problem, reached into the source code and corrected.

You can just remove the arrow and will not be able to click the buttons ;)

If the script something to remove it, then connect after dhtmlx.js the desired action
<script src="http://dhtmlx.com/docs/products/codebase/dhtmlx.js"></script>
 the <script>it needs action</script>
