const { allLang, currentLang } = useLocales();
 
return (
<>
  <RadioGroup
    row
    value={currentLang.value}
    onChange={(event) => onChangeLang(event.target.value)}
  >
    {allLang.map((lang) => (
      <FormControlLabel
        key={lang.label}
        value={lang.value}
        label={lang.label}
        control={<Radio />}
      />

Enable RTL when selecting Arabic language (Minimal UI >= v7.1.0)

This guide ensures the following behavior:

  • Selecting the AR language will automatically apply RTL (Right-to-Left) layout.
  • Selecting RTL layout will automatically apply the AR language.
src/theme/theme-config.ts
export const themeConfig = {
  ...
  direction: 'rtl'
};

src/locales/locales-config.ts
export const fallbackLng: LangCode = 'ar';

src/theme/theme-provider.tsx
  import { useLocaleDirectionSync } from 'src/locales';
 
  export function ThemeProvider({ themeOverrides, children, ...other }: ThemeProviderProps) {
    ...
 
    useLocaleDirectionSync();
 
    return (
      ...
    );
  }

src/components/settings/drawer/settings-drawer.tsx
import { useTranslate } from 'src/locales';
import { useTranslate } from 'src/locales';
 
const handleReset = useCallback(() => {
  settings.onReset();
  onResetLang();
  setMode(defaultSettings.colorScheme as ThemeColorScheme);
}, [defaultSettings.colorScheme, onResetLang, setMode, settings]);
 
const renderRtl = () => (
<BaseOption
  label="Right to left"
  selected={settings.state.direction === 'rtl'}
  icon={<SvgIcon>{settingIcons.alignRight}</SvgIcon>}
  onChangeOption={() => {
    settings.setState({ direction: settings.state.direction === 'ltr' ? 'rtl' : 'ltr' });
    onChangeLang(settings.state.direction === 'ltr' ? 'ar' : 'en');
  }}
/>
);
