Build a Family Tree website -- 2

I would like to have a website similar to this one but with some modifications: [login to view URL] The main customization required from what's already existing on the website shown is Arabic support and interface and streamlining of the tree nodes input steps. Other requirements are listed below: • Interface (Tree) - HTML5 or Javascript with high compatibility across browsers (mobile compatibility is a plus but not required) - View tree centered around the selected member (dropdown menu to choose how many levels of ancestors/descendants to show) - Ability to visualize having multiple wives and parental status (still married vs divorced) - Interface should allow user to easily add member to the tree from the graph (for example, when click on a node it shows imaginary child node that you click on to add a child) - Option to show tree in vertical format (similar to folder tree list in Windows Explorer) • Main Functionality - Export content to GEDCOM and PDF/JPG Formats - Nodes are assigned unique IDs to identify them (for example, if I want to assign a certain node a partner that’s already part of the tree, the interface should allow me to choose that person using their ID) - Ability to manage multiple Family Trees from each admin account - Option to attach images and story text to each person (in addition to regular metadata as birthdate and death date, gender (color coded nodes), birth city, current city, nationality - The site should have all the other functionality of Familyecho site that’s not covered here • Security Measure / Account Management - Two admin users to manage all accounts and make backups of the site - Admin users can create other user accounts (every account only has access to their own family trees but admins can see all tress) - Logging into the system requires a user name/ password in addition to a code that’s sent to the email address for every login (similar to banks) - The code shall be properly formatted and documented to allow for future improvements and development - I shall own the entire code generated by this project and should be able to host it on any server of my desire
