Add dir attribute dropdown feature in page properties dialog
To enable RTL support for arabic sites.
Currently there is no dir attribute in HTML element, and also we have written a sling model to dynamically choose the dir attribute based on the url/language choosen.
Need to have a dropdown for dir attributes below the language dropdown in 'Advanced' tab of page properties. Also dir="rtl" should automatically be added if we translate our contents (machine translation) from any other language to arabic.
