PDA_FDM_PrimaryConfig is the main configuration data asset for the Flexible Directional Menu system.

AC_FDM_Component, WBP_FDM_Widget, WBP_FDM_CarouselSlotContainer.
It is the central place where designers and developers configure how the menu behaves, looks, and resolves placements — without modifying code or blueprints.
You can find example Configs in FlexibleDirectionalMenu/Configuration/Configs.
