# Code folding

CLion automatically recognizes certain code structures and makes them foldable. You can also define custom folding regions.

Folded code fragments are shown as shaded ellipses (![Folded fragment](https://resources.jetbrains.com.cn/help/img/idea/2026.2/foldedFragment.png) ). If a folded code fragment has errors, CLion highlights the fragment in red.

For more information, refer to [Code folding](working-with-source-code.html#code_folding).
