I'm developing a simple component for eg. "Article Files" component and its models are "Article" and "Article Files".
When i'm creating a menu item for my component for frontend and selecting a Single Article I can't select a specific item instead the component URL is on the textbox. see the attached image. How I can fix this? I want something like the "Articles" built in Joomla whereis you can select a specific article and display it in the frontend.
