Hi,

I want to provide a preview for my custom block and I have realised the front ed forms do not render in the wp admin area. Is there a way to preview the forms in the block editor at all? at the moment by block is just blak as there is nothing to display.

setup
```
add_filter( 'rwmb_meta_boxes', function( $meta_boxes ) {
	$meta_boxes[] = [
		'title'           => 'Product Filtering Block',
		'id'              => 'dc-product-filtering-block',
		'description'     => 'Product filtering form',
		'type'            => 'block',
		'icon'            => 'screenoptions',
		'category'        => 'dc-blocks',
		'context'         => 'side',
		'render_template' => __DIR__ . '/template/dc-product-filtering-block-template.php',
		...
```
Inside 'dc-product-filtering-block-template.php' i want to call the following shortcode
```
echo $search_title;
echo do_shortcode('[mb_frontend_form id="dc-product-filtering" post_type="products" confirmation="Updated" submit_button="Update" ajax="true"]');
```
The preview of the block does not display the form but it obviously works on the front end when previewing the page.

Thanks
Nick

Hi,

Currently, it is not possible to display a frontend form in the backend, it will lead to some unwanted errors. You can read the details on the file /mb-frontend-submission/src/Shortcode.php
```
/*
 * Do not render the shortcode in the admin.
 * Prevent errors with enqueue assets in Gutenberg where requests are made via REST to preload the post content.
 */
if ( is_admin() ) {
	return '';
}
```

Hi, ok no problem. I wanted to be able to preview the form in the backend, not load the enqueued scripts. The reason being is that the block just loads a form and a title, without it there is a blank/empty block. I will have to think of a way around it then.

thanks
