Good day! I try to write custom module for OTRS.
Wrote and install "helloworld" package like in documentetion. But please tell me how write modules with many actions (like "Stats" - 3 actions) with dropdown list? Thank you.

Build up PERL and HTML, javascript and css skills.
Read the developer manual and the API description
analyse existing modules for OTRS
