            placeholder="Sele" style="width:100px">

        <option selected>@SelectedCulture</option>
        @if (SelectedCulture != "en-US")
        {
            <option value="en-US">en-US</option>
        }
        @if (SelectedCulture != "fr-FR")

        }
        </select>

    @code {
             string SelectedCulture = "fr-FR";
             private async void ChangeLanguage(ChangeEventArgs e)
             {
            SelectedCulture = e.Value!.ToString()!;
            await LanguageService.ChangeCulture(SelectedCulture);
          }

          protected override async Task OnAfterRenderAsync(bool firstRender) => await GetCulture();

        private async Task GetCulture()
        {
            string culture = (await LanguageService.GetCurrentCulture())!;
            if (culture != null) SelectedCulture = culture;

            StateHasChanged();
        }
    }

Use the component

    <div class="page">
        <div class="sidebar">
            <NavMenu />
        </div>

        <main>
            <div class="top-row px-4">
                <a href="https://learn.microsoft.com/aspnet/core/" target="_blank">About</a>
                <BlazorApp.Components.Pages.Language/>
            </div>

            <article class="content px-4">
                @Body
            </article>
        </main>
    </div>

Use the component and subscribe to Notfication Change event

    @code
    {
         @using NetcodeHub.Packages.Extensions.Localization

         @inject IStringLocalizer<AppResource> Localizer

         @inject LanguageService LanguageService

         @implements IDisposable

         @Localizer["Name"]"
         @Localizer["Email"]
         @Localizer["Password"]

         protected override void OnInitialized() => LanguageService.Notify += StateHasChanged;

        protected override async Task OnAfterRenderAsync(bool firstRender) => 
        await LanguageService.LoadCulture(Default: "fr-FR");

        public void Dispose() => LanguageService.Notify -= StateHasChanged;
      }
