Justoverclock thanks for your help 🙂
I think adding more css codes can help to other this extension's users
/* Contact-Me Extension Menu bar fix*/
li.item-locale {
vertical-align: top;
}
li.item-Drafts {
vertical-align: top;
}
li.item-signUp {
vertical-align: top;
}
li.item-logIn {
vertical-align: top;
}
li.item-Messages{
vertical-align: top;
}
(Some items can used by 3rd party extensions.)
