I am working on a new updated and complete "rtl.css" for PageLines framework. One of my problems are the arrows on drop-down menus. The arrows are not HTML Codes. They are images, and they are fine for most languages but using images makes them impossible to use for RTL scripts (Arabic, Hebrew) since they point to the wrong direction (as you see in the attached screenshot).
I tried to replace some of them with new images but I could not fix one. You can see that in the screenshot. Please let me know if you have any suggestion to fix this.
