Tips to Add Tooltip to Select2

How to add tooltip in select2

When selected text is long in select2, then it does not show the full text. So, it is very difficult to understand what is selected.

For the above problem we can solve it easily. In the select2 plug-in constructor there are  two call-back function parameters – formatSelection and formatResult that can be used to render the current selection and the result. These methods can return either a HTML string, a DOM element, or a jQuery object that renders the selection. So, in the following way we can fix the issue-

textFormat: function (item) {
  var itemText = item.text;
  return '<div title="' + itemText + '">' + itemText + '</div>';

in the select2 constructor-

formatResult: textFormat,
formatSelection: textFormat,
