I have 15 Years Experience with PHPrunner , Currently 9.8 to - 10.4. Your dropdown dependency is all dependant upon your database structure. Not withstanding that if the data needs to be generated as in your video and does not exist yet in the database then , yes you need to use either Javascript or an event before record added to accomplish this. You will also have to escape the slashes " / " if you want in that format . I can do this in an event situation before add but Javascript would be more costly and more time consuming and would be a higher bid with more time involved to accomplish this correctly. I assume you are using a MySql Database , Sql is possible also but MySQl can handle this a little easier.
