Rectangular fallback width

If the fallback shape is a rectangle and the width is specified as a number, then by default, the width value will be recalculated and randomized within a predetermined threshold (e.g. to add some variety when mulitple fallbacks are presented together). If this behavior is undesirable (e.g. in server-side rendered web apps), randomization can be disabled with the disableRandomRectWidth prop.

Alternatively, you may create a rectangle width variant by setting a number value on the rectWidthVariant prop. Variants map to a predetermined set of width values, which are cycled through repeatedly when the set is exhausted. Therefore, it's still possible to achieve some variety, but in a deterministic manner (i.e. safe for server-side rendering). Here's an example:

  const items = [{}, {}, {}, {}, {}];
  return (
    <VStack gap={1}>
      {items.map((_, i) => (
        <Fallback width={150} rectWidthVariant={i} />
      ))}
    </VStack>
  );
