Some of us find it difficult when creating documents in Arabic and want to insert a footnotes, usually the footnotes will automatically point from left to right (LTR) even though the document is set so that the text orientation is right to left (RTL).
Actually the cause of the footnotes still pointing from left to right is the wrong step in changing the text orientation from Right to Left (RTL), this is because most people change the text orientation from Right to Left via the toolbar available on the paragraph menu, this step is less effective for changing the text orientation from Right to Left (RTL) for full Arabic documents; because this step will only change the texts direction the body of the document and will not change the direction of the text in the footer where there is footnotes content.
Then what is the right step to change the direction or orientation of the text from Right to Left (RTL) for a full Arabic document? See the explanation below.
After the steps above are complete, you will see that the direction of the text in your document is completely Right to Left (RTL), please try to enter a footnotes and you will see that your footnotes is on the right side.
