Almost every control has a property called Load State which you can find by selecting the control and editing this in the Properties Panel.
When a Method user opens up a new screen, the controls on the screen can be set to an initial state.
There are three states the control can be in:
Regular - the control is visible on the screen and a user can interact with it.
Disabled - the control is visible, however it is greyed out and a user cannot interact with it. "Greyed out" is a term used when the control looks faded.
Hidden - the control is invisible to the user.
Below is an example of a button showing two states: regular and disabled. Obviously, you cannot see a button which is set to hidden.
