Toggle Buttons
Los botones de alternancia se pueden utilizar para agrupar opciones relacionadas.
To emphasize groups of related Toggle buttons, a group should share a common container. The ToggleButtonGroup
controls the selected state of its child buttons when given its own value
prop.
Exclusive selection
With exclusive selection, selecting one option deselects any other.
In this example text justification toggle buttons present options for left, center, right, and fully justified text (disabled), with only one item available for selection at a time.
Selección múltiple
Multiple selection allows for logically-grouped options, like bold, italic, and underline, to have multiple options selected.
<ToggleButtonGroup
orientation="vertical"
value={view}
exclusive
onChange={handleChange}
>
<ToggleButton value="list" aria-label="list">
<ViewListIcon />
</ToggleButton>
<ToggleButton value="module" aria-label="module">
<ViewModuleIcon />
</ToggleButton>
<ToggleButton value="quilt" aria-label="quilt">
<ViewQuiltIcon />
</ToggleButton>
</ToggleButtonGroup>
Forzar valor establecido
If you want to enforce that at least one button must be active, you can adapt your handleChange function.
const handleFormat = (event, newFormats) => {
if (newFormats.length) {
setFormats(newFormats);
}
};
const handleAlignment = (event, newAlignment) => {
if (newAlignment !== null) {
setAlignment(newAlignment);
}
};
<ToggleButton
value="check"
selected={selected}
onChange={() => {
setSelected(!selected);
}}
>
<CheckIcon />
</ToggleButton>
Botón de conmutación personalizado
He aquí un ejemplo de personalización del componente. You can learn more about this in the overrides documentation page.
Accesibilidad
ARIA
- ToggleButtonGroup has
role="group"
. You should provide an accessible label witharia-label="label"
,aria-labelledby="id"
or<label>
. - ToggleButton sets
aria-pressed="<bool>"
according to the button state. You should label each button witharia-label
.
Teclado
At present, toggle buttons are in DOM order. Navigate between them with the tab key. The button behavior follows standard keyboard semantics.
