Description

Hello,

Opengrok is very cool for code browsing, but it does't support collapsing if/else structures in C/C++ code. So it's very difficult to browse codes in functions with complex if/else sturctures. I hope opengrok can add this feature in the future.

Thanks

Research direction
Investigate the OpenGrok frontend code, particularly the syntax highlighting and code rendering components (likely in JavaScript/HTML). Look for existing collapsible code sections (e.g., for functions) to understand the pattern used. Consider implementing a toggle for if/else blocks by identifying them via AST analysis or regex patterns in the displayed code. Review any related issues or PRs for prior discussion on code folding.
