Hello, When modifying a drop-down menu in the inspector. the observable is not triggered. One other do not trigger right away. Try in the PG this : (See in the console) 1: Change _Parent_ property (the observable is not triggered) 2: Change _IsEnabled_ property (the observable is not triggered) 3 Change _isPickable_ property (the observable _IsEnabled_ it triggers now + _isPickable_ is triggered) When _isPickable_ or others is triggered, _IsEnabled_ is also triggered at this time but not when it should have been. And all the drop-down. > **[Babylon.js Playground](https://www.babylonjs-playground.com/#IBCBWA)** > > Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes ---
