# Custom Discover sliders Administrators can add a public TMDB list to Discover as a custom slider. ## Add a public TMDB list 1. Open **Discover** and choose **Customize Discover**. 2. Under **Create New Slider**, select **TMDB List**. 3. Enter a title and the numeric ID from the TMDB list URL, such as `https://www.themoviedb.org/list/1234567`. 4. Check the preview, then choose **Add Slider** and save the Discover layout. The list must be public. Private lists require an owner account and cannot be loaded by SeerrNG. List IDs must be positive decimal numbers of up to 12 digits. SeerrNG stores the list ID and slider title; it does not ask for or store a TMDB user token. TMDB movies and series appear together in the order provided by the list. A slider links to a paginated page for browsing the full list. The page follows the enabled movie and series categories, and title cards show the library and request state available to the signed-in user.
