Indicating Which Vertical Menu Button Has Been Clicked
Adrian W. West · Apress eBooks · 2016
The previous chapter described how to provide a page indicator on a horizontal menu button. This chapter uses a vertical menu, which presents us with a problem; the user might be uncertain whether a black line refers to the menu button above the line, or the menu button below the line. The solution is to add a line around the entire clicked button. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
