Is it possible to customize / add new options to the back office module advanced tab?
We already have "bootstrap size" option, but since now I'm using Bootstrap 3 I want to use 2 more extra fields for tablet and phone sizes.
I think the solution is to override the model function preprocessForm() under /administrator/components/com_modules/models/module.php and add a new line to load an extra xml..
Is it possible? how can I do it?
Thanks in advance, Pestana
