WordPress: Remove "Parent" dropdown from category form

Question

Hi I've downloaded a plugin "Simple Staff List" and it does what I need but I don't want editors to create a sub-category. How can I remove/hide the "Parent" selectbox on the form?

Add bellow code in your current theme function.php file.

add_action( 'admin_head-edit-tags.php', 'wpse_58799_remove_parent_category' );

function wpse_58799_remove_parent_category()
{
    if ( 'category' != $_GET['taxonomy'] )
        return;

    $parent = 'parent()';

    if ( isset( $_GET['action'] ) )
        $parent = 'parent().parent()';

    ?>
        <script type="text/javascript">
            jQuery(document).ready(function($)
            {     
                $('label[for=parent]').<?php echo $parent; ?>.remove();       
            });
        </script>
    <?php
}
