Speed Dial
При нажатии плавающая кнопка действия может отображать от трех до шести связанных между собой кнопок действий.
Для отображения больше шести кнопок следует использовать другой компонент вместо FAB.
Controlled speed dial
You can provide an alternate icon for the closed and open states using the icon
and openIcon
props of the SpeedDialIcon
component.
The SpeedDialActions tooltips can be be displayed persistently so that users don't have to long-press in order to see the tooltip on touch devices.
Custom close icon
Вы можете задать альтернативную иконку для закрытого и открытого состояний, используя свойства icon
и openIcon
компонента SpeedDialIcon
.
<SpeedDial
ariaLabel="SpeedDial openIcon example"
className={classes.speedDial}
icon={<SpeedDialIcon openIcon={<EditIcon />} />}
>
{actions.map((action) => (
<SpeedDialAction
key={action.name}
icon={action.icon}
tooltipTitle={action.name}
/>
))}
</SpeedDial>
Persistent action tooltips
The SpeedDialActions tooltips can be displayed persistently so that users don't have to long-press to see the tooltip on touch devices.
It is enabled here across all devices for demo purposes, but in production it could use the isTouch
logic to conditionally set the prop.
Доступность
ARIA
Required
- You should provide an
ariaLabel
for the speed dial component. - You should provide a
tooltipTitle
for each speed dial action.
Provided
- The Fab has
aria-haspopup
,aria-expanded
andaria-controls
attributes. - The speed dial actions container has
role="menu"
andaria-orientation
set according to the direction. - The speed dial actions have
role="menuitem"
, and anaria-describedby
attribute that references the associated tooltip.
Keyboard
- The speed dial opens on focus.
- The Space and Enter keys trigger the selected speed dial action, and toggle the speed dial open state.
- The cursor keys move focus to the next or previous speed dial action. (Note that any cursor direction can be used initially to open the speed dial. This enables the expected behavior for the actual or perceived orientation of the speed dial, for example for a screen reader user who perceives the speed dial as a drop-down menu.)
- The Escape key closes the speed dial and, if a speed dial action was focused, returns focus to the Fab.
