+
+## Details
+
+Pass this directive the id of the parent folder where you want the new folder node to be created.
+If no value is provided, the '-my-' alias is used.
+This will open a [Folder Dialog component](../../../lib/content-services/dialogs/folder.dialog.ts) to receive data for the new folder. If the data is valid
+then the dialog will emit a `success` event when it closes.
