Location

This defines where and how the list of options is sourced. It determines whether the combo box options are static (defined at configuration time) or dynamic (pulled from PLC memory or tags at runtime).

Direct: You manually enter fixed text options
Indirect: You reference tags that point to predefined lists via path to items that are hosted on the SD card or on a DOK (USB stick).
Dynamic: You can enter String Tags, Const Strings, or Const Tags to populate the list dynamically.

Each Option is assigned an Index Number in the List.
