Vetur/Prettier format classes in every line

I have 2 document formats for .vue files: Vetur and Prettier.

Both, formated my attr class like:

class="
  inline-block
  py-5
  px-2
  text-gray-300 text-sm
  uppercase
  font-light
"

But I prefer:

class="inline-block py-5 px-2 text-gray-300 text-sm uppercase font-light"

I changed the Width

"prettier.printWidth": 300

But same result

How can I disable that option?
