A landscape-edging device is disclosed which may be used to segregate dissimilar landscaping schemes by positioning the device into the soil. For space-saving lowering of the roof parts, it is provided that the rear roof part is pivotally supported by a third connecting rod arrangement on the middle roof part, and when the roof is lowered, is displaced over the middle roof part so that the three roof parts are deposited on top of one another in an identically cambered orientation. A dependency link associated with an event corresponding to the embedded elements is generated for describing a workflow of the components in respect to operation of the component based application when executed on a user interface of the device.
