Ask Questions and Find Answers

I am trying to implement an autocomplete dropdown which  shows all matching job title names as you type, and gives the option of adding job titles not found into the database (maybe by showing an "Add Job" button inline with the dropdown). I'm aware of some examples of how to do this in Liferay 6, but cant seem to find any examples of how to do this on Liferay 7 (except the microblogs example which is not very clear). Also the additional requirement of needing to add job titles not found -  to the database.

Please could anyone point me in the right direction?

Thanks, David
