Are there any best practices for optimizing the performance of modal forms in Symfony?

When using modal forms in Symfony, it's important to optimize their performance to ensure a smooth user experience. One way to do this is by using AJAX to load the form content dynamically without refreshing the entire page. This can help reduce the amount of data being transferred and speed up the loading time of the modal form. 

// Example of using AJAX to load modal form content

// Controller action to render the modal form
public function modalFormAction(Request $request)
{
    if ($request->isXmlHttpRequest()) {
        $form = $this->createForm(MyModalFormType::class);
        $formView = $form->createView();

        return $this->render('modal_form_content.html.twig', [
            'form' => $formView
        ]);
    }

    return new Response('This route can only be accessed via AJAX.', 400);
}
