# what should happen to a prominent app bar with long and two-lined title, when scrolling

In material design, if the title is long we should put it in a prominent Appbar like this:

The title should not be truncated or shrunk. so when the content scrolls up, should I transform the prominent Appbar to normal? If so, what would happen to the long title, as it should not be truncated or shrunk? Or we should let it be in this way all the time?

• Material Design isn't gospel, if changing it to a normal app bar and making the title smaller suits your users and your application, it's hard to argue against that. Google give you the rule-set which, if followed, makes your app conform to MD. – DarrylGodden Jul 10 at 14:56
• @DarrylGodden thank you, But does MD has a rule-set for this situation? it is not mentioned in the Material Design website. – Ali Kazemkhanloo Jul 10 at 15:06
• Reading MD I would say they are suggesting the title should persist and you should give up the space. – DarrylGodden Jul 10 at 15:15

Whenever you ask something of the user you’ll need a fallback. If the user hasn’t uploaded their logo, you can default to their name, which can be truncated for space and appended with an elipsis ….
