Hello there
I would like to implement an input form for creating users tags, basically the same one that is here when creating new thread (also with that live search 
)
I have many to many relation between user and tags (interests).
Because app is designed for mobile, form could be on standalone page.
Also, I`m newbie so try to explain as much as possible 
When I decided to give Elixir a try I didn’t know I would understand and enjoy it quicker than all my other attempts (Ruby, Rust, Go, PHP, Java, JavaScript, whatever…) thank you for keeping me interested.

I think a tutorial is what you are looking for.
Maybe this one: Making a unified tagging system with many to many ecto relations.
Although I have not tried it myself, I think it will probably come in handy in your quest. ^^
