placeholder Function | String | jQuery
Provides a way for customization of the sortable item placeholder. If a function is supplied, it receives one argument - the draggable element's jQuery object. If placeholder function is not provided the widget will clone dragged item, remove its ID attribute, set its visibility to hidden and use it as a placeholder.
**Important: The placeholder element is appended to the Sortable widget container.
Example - Sortable with custom placeholder
<ul id="sortable">
<li>ItemA1</li>
<li>ItemA2</li>
<li>ItemA3</li>
</ul>
<script>
$("#sortable").kendoSortable({
placeholder: function(element) {
return element.clone().css({
"opacity": 0.3,
"border": "1px dashed #000000"
});
}
});
</script>
