Meta Box

Hello Melissa,

The custom field does not have a category (taxonomy) like that, only post type has. You can create a CPT reviews and set the relationship with the CPT services and create taxonomies for the reviews CPT.
Refer to the documentation https://docs.metabox.io/extensions/mb-relationships/

Hello,

It sounds like the plugin Admin Columns Pro which allows users to edit the field value in the posts table. Meta Box has an integration plugin with this.

Hello,

I've tested this issue with PHP 8.2 and some variables from Insert Fields tab but do not see that. It might relate to your custom code added to the view content.

You can remove one-by-one lines of code to find what causes the issue.

Hello,

MB Builder does not support an option to duplicate the field group. It could be a feature of a third-party plugin that causes the issue.

Hello,

If you are familiar with coding, you can follow this topic to create a custom frontend dashboard on your own https://support.metabox.io/topic/duplicate-dashboard-shortcode
the post list in the dashboard is just created by a WP query.

Hello,

Please follow this topic to use some PHP code to auto-login after registration https://support.metabox.io/topic/how-to-set-auto-login-after-a-successfull-registration-page/

Hello,

I use the code below to print all elements of the $_POST object and still can access the field value as well.

add_action( 'rwmb_frontend_after_save_post', function( $object ) {
    echo "<pre>";
    print_r( $_POST[] );
    echo "</pre>";
    die('12345');
} );

Hello,

It's the customization code for your specific needs so it is beyond our scope of support. FYI, the iframe is not available on the page load, it is available when clicking on the button "Add New Post". You can listen to the body change to do stuff.

For example:

jQuery(document).ready(function($) {
    $('body').on('click', '.rwmb-post-add-button', function() {
      $('body').find('#rwmb-modal-iframe').on('load', function () {
      		$(this).contents().find("#wpwrap").css("background-color", "red");
      });
    });
});
