Why is my question a shopping type of question? I really do not understand?

Why do people mark a question to be closed without any note/explanation? I asked and later it was marked to be closed by 2 people. Without any comment nor an answer. I don't agree with @Chris S but he left his explanation. Than you for that. That's called 'collaboration'.

I do not think that any (free script or product) thing like I am asking about exists but before coding what I want by myself I asked here. What is bad about it?

If the best answer to a question is name of a product that means that it is a shopping question?
