How can I create a parent menu for my languages and insert them into the main menu?

I am using Bootstrap and when I see the menu in the mobile version the menu of languages is out of place, that’s why I would like to put them inside a parent one called languages that appears inside the main menu.

Thanks in advance.

Can you provide details? What CMS are you using? Can you include a link?

Sure,, I did it in a dirty way, when it goes to mobile I did create a manual menu.
