25### Title Bars on Non-level-1 Screens
26
27- The title of a non-level-1 screen is the name of the screen.
28- Place a maximum of three icons on the right. Alternatively, you can choose not to place any icon.
29- The main title and subtitle are optional. In the case of a two-line title, the title of the second line provides auxiliary description for the title of the first line.
30- [Not recommended] If there are multiple views but all other views except the default view are seldom used, you can use the drop-down menu title. However, this practice hides the content in the drop-down menu title and reduces their usage. Therefore, it is not recommended.
