Users interact with navigational components in order to move throughout an application - or move through elements and forms within an applicaton.
These sliding areas, usually indicated by arrows, should be offered when the content within a section is too much, or spreads to far, to contain within the section.
Below are a few examples of sliders:
In the first example, there are too many segments within this trip to display them all on the upper section. The user can use the slider arrows to navigate over to outlying segments so they can access them. The second example is a similar situation.
An image slider is another good example of content that can be scanned via a slider within the slider area.
