Language – multiple options

Hi all,

Running a site (Drupal 7) for a charity NGO and we would like to add the option of navigating in several languages (specifically adding French and maybe Arabic in the future.

We are not looking to translate all the content, but more just have a button (e.g. a flag) you can click in a corner that would translate all navigation tools and maybe some pages, too. I understand we would have to manually input most of the translation ourselves, but we are can accomplish this. It’s just a question of enabling the function that is proving difficult!

I’ve been having difficulty with this for some time, so would really appreciate any pointers on how to achieve this.

Thanks in advance!
