title: How do I implement tagging in web app post? Like how questions on stackoverflow have tags?
body: <p>So I have a form where a user can post a project. He fills the fields and submits so far. However what I would like is to use a tag system where instead of writing a string of skills needed for the project, they should be tags. Then implement a tag based search. Kind of like here on stackoverflow you can search questions based on tags. I'm not sure what to google or what kind of question I am looking for. Maybe someone can point me in the right direction?</p>
