Add a ModFrame component

The user can either add a ModFrame component with the tool bar, menu or by dragging the component in to the configuration panel from the components tab. The last option enables the user to place the component in the panel initially, but the top application must be added by the two first options since the configuration panel does not exist.

Either one of the options will display the add component dialog. The user can select from the list and choose an appropriate name of the new component. If a component with the name supplied already exists in the container.
