Can i rename menus in dashboard

I don’t really get what you try to achieve. Do you want to change the menu name in the admin panel? Please provide a screenshot where you are trying to change the menu name

You can add this code in your theme functions.php file

add_filter( 'gettext', 'change_projects_label', 10, 2 );
function change_projects_label( $translation, $text ) {
if ( $text == 'Projects' )
    return __('your_title_label','your_theme');
return $translation;
}

Replace ‘your_title_label’ and ‘your_theme’ and add the translation to your .po language file with apps like poedit
