Webshim: How to set no spinbuttons option statically -

i tried remove spin date control:

$.webshims.setoptions('forms-ext',   {      replaceui : true,      date :        {        nospinbtn : true,        startview : 2       }   }); 

tried other variants, never succeeded.

is there documentation? similar cases set 'position' property.

here config examples datepicker. removing spin-buttons simple. need css:

.date-input-buttons .step-controls {     display: none; }
