Lookups are the standard way to display a list of possible selection values to the user, while editing or creating database records. Normally, standard lookups are created automatically by the system in Dynamics 365 for Finance and Operations and are based on the extended data types and table setup. It is also possible to override the standard functionality by creating your own lookups from the code or using the Dynamics 365 for Finance and Operations forms.
In this chapter, we will cover various lookup types, such as file selector, color picker, or tree lookup, as well as the different approaches to create them.
