Click the "Add Fields" button in the top right corner. Select the "Dropdown" field from the list of available fields. Enter the name of the dropdown list in the "Name" field. Enter the list of options for the dropdown list in the "Options" field.
Picklists are physically different from database lookup fields since there is no foreign key relationship between the tables. The application generator automatically configures lookup fields. Developers can configure a picklist on any field in a web application.
Select versus Dropdown A select presents a list of options from which the users can select only one item from that list. It works best in forms when users choose an option from the select list and submit data. A dropdown presents a list of options that users can select one or several options from that list.
The SelectBox has only a list of items in a drop-down field whereas Lookup also has a search field and the Cancel button. The SelectBox looks the same on any platform, while Lookup changes its appearance. The Lookup's drop-down field is replaced with a popup window that occupies most of the screen.
Most drop-down list values are configurable by your administrator. Lookups are available in certain fields and give you the ability to search for and select records from either the database or from values that were defined by your enterprise.
