If I run it in browser, dropdown effect and popup effect work's good,

Electron cannot find your jQuery instance.

To do this, you have to deactivate the node integration. This automatically changes everything to CommonJS. Important! If it is deactivated, you cannot use Electron.NET IPC communication. Then please use the standard communication from Blazor with your C# code.

Start without node integration:

Task.Run(async () => {
    var browserWindowOptions = new BrowserWindowOptions
    {
        WebPreferences = new WebPreferences
        {
            NodeIntegration = false
        }
    };
    await Electron.WindowManager.CreateWindowAsync(browserWindowOptions);
});

Then it works:
