@fenz: Catch Everest Pro theme don’t have RTL support. So, everything has to be done though Custom CSS. You can add the following CSS in “Appearance => Theme Options => Custom CSS” box.
/* Space Between Menu */
#header-menu ul.menu a {
padding: 0 15px;
}
/* Sub-menu text align */
#header-menu ul.menu li {
text-align: right;
}
/* Header Image in Right */
#header-left {
float: right;
}
/* Search Column in Left */
#header-right {
float: left;
}
Note: You can send us Arabic translation and then we can add RTL support. So, you have all this done automatically in new version update. If you want this then please contact through http://catchthemes.com/contact-us/
