Hi guys,
Recently i decided to change direction of some elements from ltr to rtl inside index.jsp page
I try to do this with some modification in styles.css file but because of cascading feature it will not work for elements which have inline style in html.I want to know where this inline styles added to elements ?
I'm using Openkm-6.3 Community edition using configured linux environment(ova)
Thanks in advance

For example:
We have a division with class "gwt-MenuBarPopup okm-TopMenuBarPopup" for showing menu popup when we click on each menu item.
it has some inline styles like style="left:818px,top:25px..." that made it appear from the left side of related menu item .now i need to change this inline styles to show the popup menu from right side of menu item.Shere i should modify the style ? does this inline styles sets dynamically with GWT ?

For better understanding of this kind of question, will be better if you share some screenshot like I have attached. I think left position only is settting the position of the popup for centering in the screen ? I'm not sure if we are talking about the same.
