Multiple dropdowns on a graphical user interface (GUI) are dynamically linked at runtime. The dropdowns are associated with inter-related attributes of an object displayed on the GUI. The content of each dropdown includes a list of values of an attribute and is entirely or partially hidden until the dropdown is selected. The list of values of each dropdown are dynamically generated and rendered at runtime, using stored data that links the attributes to their parent attributes. The stored data can be dynamically updated to reflect currently-available attribute values and the relationship of the attributes.
