This brings us to the Properties panel. All components have properties, and the Properties panel is where we view and edit those properties. The Accordion layer of Properties is the primary interface for defining component behavior. Properties shown depend on the selected component in the model, as not all properties are common to all components. Each layer in the accordion groups properties into common categories such as events and style.
Properties can be viewed in Recommended or All mode. In All mode, all properties are shown straight off. In Recommended mode, the properties shown are reduced to the recommended set. The recommended properties are the most commonly used properties. These also tend to be less dangerous if you don't fully understand them. If there are additional properties beyond the recommended ones to be had, you can show them without leaving Recommended mode by clicking on the Show more link at the bottom of the set.
