Hello. Tags can be altered using scripts from the Fandom Open Source Library. Collapsing is a standard class, as explained here. I'm not sure what you want to do specifically with the railmodule or header -- you might start with Help:Customization and follow links from there. Or you could create a thread requesting specific help for what you want to do. Good luck!
