Details
A DropDown is a list based control that when clicked expands to show the list of available values.
Depending on configuration, a DropDown can also allow data entry in the edit portion of the control.
When an item is chosen from the DropDown, the field values associated with underlying list entry will be returned to the parent component.
Prim_list.Dropdown is a variation of PRIM_LIST. The result is that the drop down list itself supports nearly all of the functionality available to standard list. Dropdowns therefore can have a tree in the drop down portion or use reusable parts for individual cells so that the list can be formatted in a countless number of ways.
