Learn the trick to making specific words appear bold in Select2 by changing the font style

I'm currently working with select2 version 4.0.1, and I have a requirement to modify the font for specific words. In particular, I want to display codes AK and HI in a different/bolder font style, similar to the example below:

<select id="select2" style="width:300px">
    <optgroup label="Alaskan/Hawaiian Time Zone">
        <option value="AK"><strong>AK</strong> Alaska</option>
        <option value="HI"><strong>HI</strong> Hawaii</option>
    </optgroup>

Is there a way to achieve this? How can I implement it?

Answer №1

To achieve this, you can follow these steps. Use the templateResult function to customize the option text as select2 is being created:

HTML Code:

<select id="select2" style="width:300px">
  <optgroup label="Alaskan/Hawaiian Time Zone">
    <option value="AK">Alaska</option>
    <option value="HI">Hawaii</option>
  </optgroup>
</select>

JavaScript Code:

$('#select2').select2({
  templateResult: formatOutput
});

function formatOutput (optionElement) {
  if (!optionElement.id) { return optionElement.text; }
  var $state = $('<span><strong>' + optionElement.element.value + '</strong> ' + optionElement.text + '</span>');
  return $state;
};
