Fz Whether the widget will be disabled when rendered. If ``True``, the widget will be greyed-out, and not respond to UI events. Zfixeda^ How the item being displayed should size itself. Possible values are ``"fixed"``, ``"scale_width"``, ``"scale_height"``, ``"scale_both"``, and ``"stretch_both"``. ``"stretch_both"`` elements are completely responsive (independently in width and height) and will resize to occupy all available space, even if this changes the aspect ratio of the element. This is sometimes called outside-in, and is a typical behavior for desktop applications. ``"fixed"`` elements are not responsive. They will retain their original width and height regardless of any subsequent browser window resize events. ``"scale_width"`` elements will responsively resize to fit to the width available, *while maintaining the original aspect ratio*. This is a typical behavior for modern websites. For a ``Plot``, the aspect ratio ``plot_width/plot_height`` is maintained. ``"scale_height"`` elements will responsively resize to fit to the height available, *while maintaining the original aspect ratio*. For a ``Plot``, the aspect ratio ``plot_width/plot_height`` is maintained. A plot with ``"scale_height"`` mode needs to be wrapped in a ``Row`` or ``Column`` to be responsive. ``"scale_both"`` elements will responsively resize to for both the width and height available, *while maintaining the original aspect ratio*. )defaultra A list of CSS class names to add to this DOM element.
