Add support for TMDB List IDs in Custom Discovery Sliders

[yannskee]

🧭 TL;DR

Let admins turn any public TMDB List into a custom Overseerr discovery slider — with full control over sorting.
Perfect for ranked or themed collections like “NYT’s Top 100 Movies of the 21st Century,” “Halloween Horror Picks,” or “Oscar Winners.”

🧩 Problem

Currently, Overseerr admins can only create custom discovery sliders using built-in filters like Genres, Keywords, Studios, or Networks.
There’s no way to create a slider based on a curated TMDB list — whether personal or public.

That means if you want to highlight something like “The Top 100 Movies of the 21st Century” or “Best Sci-Fi Classics”, you can’t do it directly within Overseerr without external tools or workarounds (like Plex collections).

This makes it impossible to showcase hand-picked, ranked, or thematic media collections in a native way.

🎯 Use Case

As an admin, I want to feature a specific TMDB list as a discovery slider —
for example, the New York Times “Top 100 Movies of the 21st Century.”

I’d like the slider to display these movies in the same order they appear on TMDB,
which typically corresponds to the order they were added to the list (ascending).

Ideally, future versions could include an option to choose different sorting types —
but even just supporting the “Added Date (asc)” order would already make curated lists fully usable for discovery.

💡 Proposed Solution

Expand the Add Custom Slider feature to include support for TMDB Lists with sorting options.

1️⃣ New Slider Type: “TMDB List”
Add a new option under
Settings → Discover → Add Custom Slider → Type → List

2️⃣ Input Field for TMDB List ID
Admins can paste a TMDB List ID (e.g. 8209876).

3️⃣ No Extra Auth Required
The list is public

4️⃣ Sorting Options
Admins can control display order:

• 🥇 Original (Curated Order) — Respects TMDB list ranking/order
• 🕓 Added Date (asc/desc)
• 📅 Release Date (asc/desc)
• 🔤 Title (asc/desc)

5️⃣ Display Behavior
The slider should behave like any existing one (e.g., “Popular Films”), showing clickable posters that lead to the standard request page.

Additionally, clicking on the slider title should ideally open a dedicated listing view (e.g., /discover/tmdb-list/:id) displaying the full list in grid form — similar to how existing routes like /discover/trending or /discover/upcoming behave.

If implementing a dedicated route isn’t feasible right away, simply disabling the clickable title or linking it to TMDB’s public list URL would be an acceptable fallback.

🧠 Technical Reference

Public TMDB lists can be fetched via:

GET https://api.themoviedb.org/3/list/{list_id}?api_key=<<api_key>>&language=en-US

Each item already includes the necessary metadata (media type, title, release date, order).

💬 Community Impact

This feature would unlock huge flexibility for admins and richer discovery for users.
It’s simple, native, and leverages Overseerr’s existing TMDB integration.
