Hi there

It's my first time here and I'm also quite new to coding and css
I'm practicing on building a site (http://www.drbenshlomo.com/)
it's a Wordpress site, and in Hebrew, i'm basing on templates and pluguins but everything must work from right to left there. I can manage most of the issues but I can't get the Flyout menu to open to the left instead to the right as is at the moment.

Can anyone point me how make the menu open (flyout) to the left?

Thanks a lot
Eq
