To create and edit component contents, change component properties, and move a component, the component must be selected by clicking on it.
When selected, a component will have four handles around it.
Clicking on another component deselects the first.
When you select a component, component-specific options, groups and tabs will appear on the ribbon. For example, when you select a view component, a set of view-specific tabs will appear on the ribbon, as well as view-specific options in the Component group of the Design tab.
