Thank you for sharing this great project.

How can i call leanModal inside an conditional IF?

I have an if inside an $( document ).ready(function() { if(){}}

I just try:
$( document ).ready(function() { if() { $("#submitButton").leanModal(); } }

The modal does not open, i check the files (CSS/JS) and they are declared .

Could you please provide an example, i think it is a very commom situation.
