Propriétés

Propriété	Type	Par défaut	Description
`orientation`	`'vertical'\|'horizontal'\|'both'`	`'vertical'`	The direction in which the content scrolls.
`label`	`string\|null`	`null`	The name of the region, read by screen readers; it makes the box reachable at the keyboard.

Accessibility

With label, the box is a named region that the keyboard reaches and scrolls with the arrows (WCAG 2.1.1). Without it, the browsers of today make a scroller without focusable content reachable themselves.
