Are there solutions for dropdown tooltip for words in text like facebook or twitter friends?

Question

JavaScript

Here on Facebook or Twitter, if you start writing a friend's name or a hashtag, then a drop-down list with tips immediately appears. I googled, but didn't find anything suitable - all sorts of autocompletes for selects get in the way everywhere.
Does anyone know a suitable solution?

UPD. Here is an example picture

Answer 2

Well, in fact, I’ve been implementing this for a long time, it was like an option to make a query to the database when you enter something in the search bar, from there select the first 5 options, let’s say, insert them into the block allocated for the output of options, it seemed to work well, so if nothing you will not find a way, you can use this solution.
