Is it possible to change the width of the suggestion list?

See here: https://codepen.io/anon/pen/vdMdxB

If you start to type "Aus" then I want to see the full value:

I see that the width is same as the input text field width: https://github.com/Pixabay/JavaScript-autoComplete/blob/master/auto-complete.js#L68

Is there any specific reason for that? ( how can I overwrite that? )
