This command, which is also available in the context menu of the Files Pane, opens a File Open dialog box, in which you can browse for the MobileTogether Designer project file (.mtd file) that you want to add as a subproject of the current project. After selecting a server action library file and clicking Open in the Open dialog, the file will be added as a subproject and will appear as such in the current project's Files Pane.
|If the file you want to add as a subproject contains a visible top-level page, then the file cannot be added as a subproject. You will receive an error message to this effect and a suggestion to assign all top-level pages in the project that you want to create as a subproject to a hidden module that will not be exported. For information about how to do this, see the topic Modules.
