 ## Consuming input
 Each Gooey component has a ```consumed``` variable in its state stable. Consuming input in a gui_script to prevent input propagation can be done by checking the consumed state of each component. If any component has ```consumed``` set to true it is safe to return true from the ```on_input()``` function to prevent input propagation. It is also possible to wrap all component interaction in an input group and check the consumed state for the entire group:
