Good evening,
thank you so much for your response. Eventually I discovered that we can shorten letters.
The problem is that the theme settings> mobile menu setting is only for the size of the characters in the main menu.
To set the character size in the submenu, I have to go to the submenu items and adjust the character size for the submenu of the computer as well as the mobile phone. The result is that the size of the computer screen is small and mobile is normal.
Thank you
