      Args:
          children (list of :class:`~bokeh.models.widgets.widget.Widget`): A list of widgets.
  
          sizing_mode (``"fixed"``, ``"stretch_both"``, ``"scale_width"``, ``"scale_height"``, ``"scale_both"`` ): How
              will the items in the layout resize to fill the available space.
              Default is ``"fixed"``. For more information on the different
              modes see :attr:`~bokeh.models.layouts.LayoutDOM.sizing_mode`
              description on :class:`~bokeh.models.layouts.LayoutDOM`.
  
      Returns:
          WidgetBox: A column layout of widget instances all with the same ``sizing_mode``.
  
      Examples:
  
          >>> widgetbox([button, select])
          >>> widgetbox(children=[slider], sizing_mode='scale_width')
