Add subsections to the Design Patterns section (A copy of a closed problem, because it is relevant)

Judging by the number of likes the problem closed today, I still decided to create another one with the same quest, please do not ignore it, learning GOF patterns is an important step in backend developer learning

Please add subsections to the Design Patterns section like: (These are 21 classic GOF patterns)

PATTERNS

• Creational Abstract Factory Builder Factory Method Object Pool Prototype Singleton
• Structural Adapter Bridge Composite Decorator Facade Flyweight Private Class Data Proxy
• Behavioural Chain of responsibility Command Interpreter Iterator Mediator Memento Null Object Observer State Strategy Template method Visitor

If it would complicate the tree structure that much, maybe at least change the Design Patterns section by removing the popular ones (Popular ones?), leaving only three items of the pattern types themselves, namely:

• Creational
• Structural
• Behavioural

So that those who study patterns would have a framework to study and be able to find information on each type on their own?
