A dynamic tracker list is a list field whose options will dynamically change, based on another selection.

For example, we can extend the tracker form we created previously to allow users to select their operating system: Windows or Solaris. Then, depending on their selection, Tiki will automatically display a different list of valid options, depending on which operating system was selected.
{NOTE()}Refer to the Tiki Documentation Tiki for complete information on dynamic lists.{NOTE}

To accomplish this, we'll create a separate tracker to maintain the operating system values. We'll refer to this tracker as the Internal tracker. We'll refer to the tracker that users will directly interact with as the External tracker.

In this section we'll create the "Internal" tracker and then link it to the "External" tracker.
