For the app I am currently developing, I have a vertical navbar which contains the main menus required for the user. One of the menus is for User Admin, which is a profile picture with the User's first name under it.
I am having a think about how I should deal with extra long names in this field. The navbar is obviously a fixed width, and so deals with about 10-12 characters (depending on character used) before starting to overflow.
Names over this length are somewhat in the minority, but I don't want to have a lot of overspilling elements if I have to use their name in other locations within the app, and i'm not sure how I feel about truncating the name or adding a "..." etc.
Is there an assumed best practice when dealing with this kind of issue?
