Display only in a specific OpenCart category?

Question

opencart

Hello! Need help. I don't understand PHP very well.
I need one function to work only on one specific category and its subcategories.
This can be done somehow through if else by specifying the category id by setting a condition. Please tell me how to make this function work only for 1 category and its subcategory.
I hope I explained clearly. I thank you in advance!

Making conditions for specific categories is bad practice. It will be better for another category to define a different pattern. There is such a free module that can do this without crutches: https://opencartforum.com/files/file/1986-personal...
