Allow "x Selected" to keep the item single-line

[JPustkuchen]

Thank you very much for this great plugin.

Just a little enhancement idea: Could you add an option to keep the element single-line if more items than the width of the element are selected?
For example https://github.com/HemantNegi/jquery.sumoselect does that.
Or the selected items could end on "..." at the end of the line to indicate that there are more item selected.

There are several cases in layouts (compared to other native inputs (as filters e.g.)) where multiline is a problem.

Thank you very much again.
