# ChatGPT Sidebar GPTs — Fold/Unfold List
## Fold the ChatGPT sidebar custom GPTs list. Show only 3 by default and add a “See more (n)” button to expand or collapse the rest.
This userscript improves the ChatGPT sidebar when you have many custom GPTs.
By default, ChatGPT shows the entire list, which can be long and cluttered.
With this script:
- Only the first 3 GPTs remain visible.
- A button “See more (n)” appears right after them, where n is the number of hidden GPTs.
- Clicking expands the full list, and the button changes to “See less”.
- Works dynamically: the script uses a MutationObserver, so it updates automatically when the sidebar changes.
- Minimal CSS, no breaking changes to the native UI.
✅ Compatible with Tampermonkey, Violentmonkey, and Greasemonkey.
✅ Works on chat.openai.com, chatgpt.com, and openai.com.
✅ Lightweight and ESLint-compliant.
