How to solve the issue of only displaying modules and not projects in the idea.

If you want to hide the name of the project and only display the module name, you can consider the following methods:

1. Use module aliases: Set an alias for each module in the code, and then only display the alias when shown, rather than the actual name of the module. This can hide the project name of the module and only display the module name.
2. Organize the project into modules using a folder structure, where each module is contained within its own folder named after the module. Display only the folder name when showing, without showing the specific project names inside the folder.
3. Use comments: In the code of the project, use comments to indicate the name of each module, then only display the module name from the comments when showing it, instead of showing the actual name of the project.

You can choose and adjust the above methods based on your specific situation, hoping it will be helpful to you.
