Unknown prop sortHandle on <div> tag

It guess that this warning is caused by React not allowing unknown props, but anything I can do to fix this?

Try this

import React, { PropTypes } from 'react'
import { SortableItemMixin, SortableContainer } from 'react-anything-sortable';

var SortableItem = React.createClass({
  mixins: [SortableItemMixin],

  render: function(){
    return this.renderWithSortable(
        <SortableContainer {...this.props}>
            <div>your item</div>
       </SortableContainer>
    );
  }
});
