Currently I am testing with 'M.util.show_confirm_dialog' function - all works fine, but this is a confirmation popup box.
As I get it, I need to develop a new JS-module or copy and modify 'M.util.show_confirm_dialog'.
Documentation states I need something called Grunt and says how to install it on Linux via terminal. But I run Moodle on MS Server 2012 R2. And so, what to do?
Do I need this Grunt for my purpose? Something else?
Need help.
