The context parameter in the GetItemsAsync method of the IPropertyUIHandler interface does not have any data.

My current requirement is as follows: There are two inputs. The first input is a dropdown selection box for device type, and the second input displays a dropdown selection box for device attributes based on the selected device type. However, without any contextual information, I am unable to obtain the data from the first input box to display the data in the second input box.

Or is my implementation approach incorrect? Please provide guidance. Thank you.
