Pass value to Select2?

Question

JavaScript

There is on the Select2 page, in data I pass an array with id, text (this is how select2 accepts).
But for "templateResult" I want to pass one more parameter to the array, but then select2 does not display the array correctly due to the fact that not 2 values ​​were passed, but already id, text, myParam. How can this be rewritten correctly?

Answer 1

A little wrong. In order to set additional parameters for the select options, they need to be placed in the widget options:

echo Select2::widget([
    'name' => 'my-select2',
    'data' => [1 => 'One', 2 => 'Two'],
    'options' => [
        'placeholder' => 'Select a number ...',
        'options' => [
            2 => ['disabled' => true],
        ]
    ],
]);

Should output:

<select>
  <option value="1">One</option>
  <option value="2" disabled="disabled">Two</option>
</select>
