I tried for two hours to RTLize\Flip the module via Firebug & Style.css but without major success. So I figured this is one of case when the flipping should be done at the module's CSS files themselves. So I went to
sites/all/modules/accordion_menu but I couldn't find anything that has all the CSS. I found only
accordion_menu.css that doesn't have more than 4-5 rows of CSS code. So it's not something I could RTLize\flip.
Therefore I ask, where is the genuine Accordion Menu CSS file (that appear in DOM but not in the style window)? How could I track it down and flip it's CSS?
