Clear/Close buttons not visible.

No amount of settings allow the clear and close buttons to show.

You can edit the code and change the var controls = '<div class="ui-datepicker-controls"...>' to '<div class=""..>' or in the css set the 'ui-datepicker-controls' style to remove the "display:none".

However this brings up a secondary issue. The ui code surrounds the "clear" and "close" with div tags so the "Clear" and "Close" appear vertically aligned to the left which looks bad. As all the "HTML" is embedded in the source, its impossible to tweak it they way you want. At very least doing something akin to the following for the controls section looks better, and requires less vertical room (you generally have more horizontal than vertical)...

<div class="ui-datepicker-controls">

<span class="ui-datepicker-clear"></span>

<span class="ui-datepicker-close"></span>

</div>

ui-datepicker-controls { text-align: right; }

ui-datepicker-clear { float: left; }

ui-datepicker-close { text-align: right; }
