This option is only available if a component is selected in the Navigation Pane. It is equivalent to pressing the button on the Menubar.
Choose this to remove the currently selected component from the Navigation Pane and stop it from being managed by EMM.
You can also remove a component by selecting it and pressing the Delete key.
By default, EMM displays a confirmation dialog providing the option to cancel the removal of the component, as shown below.
If the component is known to be running, as well as providing the option to cancel the removal the dialog asks whether the component should be stopped before being removed, as shown below.
Note: Warnings describes how these confirmation dialogs can be turned on or off using the EMM Preferences dialog.
