A list box represents the list of all the values of a specific field. Selecting a value in the list box highlights the related values in other sheet objects. This helps in faster visual analysis. It is also very useful to follow a drill-down path among various sheet objects. It also has a search feature, which allows to search for specific values in the list box which is very helpful for a very long list of values.

Search Option in List Box
When the List Box contains a very large number of values, it is difficult to scroll down and look for it. So the search box at the top of the list box can be used to type the search string. The relevant values appear as soon as the first letter is typed.
List Box and Association
Other Sheet Objects automatically get associated with the List Box and the association is easily observed by selecting values from the list box.
