I am trying to bind onclick to select input element with select2 initialization.

I want to bind a handler when the drop-down is clicked or focused.

<select class="form-control" id="type" name="type" required="required">
    <option value="breakfast" <?= ($type == 'breakfast')? 'selected' : '';?>>Breakfast</option>
    <option value="snacks" <?= ($type == 'snacks')? 'selected' : '';?>>Snacks</option>
</select>

Here's the js part:

$('#type').select2({}).on("select2-selecting", function(e) {
    console.log('not working');
});

I also tried "select2-open/opening" but to no avail. How do I make the event binding work?

In the version 3.5.1 you're using, you should use select2-selecting instead of select2:selecting like :

$('#type').select2({}).on("select2-selecting", function(e) {
    console.log('not working');
});


$('#type').select2({});

$('#type').on("select2-opening", function(e) {
  console.log('Opening');
});
$('#type').on("select2-selecting", function(e) {
  console.log('Selecting');
});

For Version 4.0 + you can use below.

$('#yourselect').on("select2:select", function(e) { 
   // what you would like to happen
});
