An Index Field without a List is the default setting in GlobalSearch. There are two types of Field Lists; Standard, and Dynamic.

Pick Lists

A Standard Pick List is a list of choices for the Field where users may select a value. It can be set as either a drop-down or a type-ahead type of list.  Standard Pick Lists can of a Dropdown or Typeahead style.

 A Typeahead List provides a suggested list of values as users type data into a Field. A Type Ahead List field is particularly useful for data values which are frequently misspelled, long, complex, or otherwise time-consuming to type, such as customer or company name.  Typeahead lists offer suggested input that can be selected, but can also be overridden by the user.

Dynamic Pick Lists

A Dynamic Pick List allows you to filter drop-down fields in a pick list based on information selected in a separate, related field. Pick lists used to build Dynamic Pick Lists must be drop-down lists and the Dynamic Pick List cannot be a Multi-Value List. Use a Dynamic Pick List, for example, to first select a car from a list of vehicle manufacturers; it will then show only models based on the make of car selected.
