Place your date picker within an element on the page, say:
<div style="display:none">
<div id="dpContainer">test 1<input type="text" id="datepicker" /></div>
</div>
Then you can specify how the tooltip will be launched from a target element:
<span class="tooltip" onmouseover="tooltip.pop(this, '#dpContainer')">
Hover me
</span>
Let me know if it works or not. Thank you.
