[opencms-dev] hide advanced button in properties dialog

[mashhur sattorov]

Hi all!
I am really new at OpenCMS and I have never use such systems, however, I can write a Java program (OOP). So, I installed this CMS successfully but i do not know at the beginning what kinds of books should i read? I read some books, such as OpenCMS 7.0 for Developers but I understand nothing. Could you do me a favour ? How can i create my own module and right now what should i do?
Thank you in advance!
best regards Mashhur!
