[RichWidget] Input Calendar triggered by Button and setting the "Step" value

[RichWidget] Input Calendar triggered by Button and setting the "Step" value

  
Hi,

Is there a way to activate the input calendar by push of a button instead of entering (focus) the field ?
I've seen there is a parameter "button" which should do the trick, but that one is not a parameter of the actual richwidget

<script type="text/javascript">
    Calendar.setup({
        inputField     :    "f_date_b",      // id of the input field
        ifFormat       :    "%m/%d/%Y %I:%M %p",       // format of the input field
        showsTime      :    true,            // will display a time selector
        button         :    "f_trigger_b",   // trigger for the calendar (button ID)
        singleClick    :    false,           // double-click mode
        step           :    1                // show all years in drop-down boxes (instead of every other year as default)
    });
</script>


And anybody know how to set the STEP parameter for the year dropdown ?
