Dynamically changing Inputs on option selection in a DropDownInput

[unannn]

Feature Request

Whenever I select an item in options via DropDownInput, I want to dynamically show the inputs at the bottom depending on the item (the inputs can be one or multiple depending on the item).

However, the update_build_config method is not called every time I select an item in options. Is there any way to make it so that I can modify build_config every time I select an item in options?

In the current situation, the Inputs are dynamically generated on the first selection, but when I try to select another item, I get the error below.
