How to use placeholder as default value in select2 framework

You have to add an empty option (i.e. <option></option>) as a first element to see a placeholder.

From Select2 official documentation :

"Note that because browsers assume the first option element is selected in non-multi-value select boxes an empty first option element must be provided (<option></option>) for the placeholder to work."

Hope this helps.

Example:

<select id="countries">    <option></option>    <option value="1">Germany</option>    <option value="2">France</option>    <option value="3">Spain</option></select>

and the Javascript would be:

$('#countries').select2({    placeholder: "Please select a country"});

Put this in your script file:

$('select').select2({    minimumResultsForSearch: -1,    placeholder: function(){        $(this).data('placeholder');    }});

And then in HTML, add the following code:

<select data-placeholder="Your Placeholder" multiple>    <option></option> <------ this is where your placeholder data will appear    <option>Value 1</option>    <option>Value 2</option>    <option>Value 3</option>    <option>Value 4</option>    <option>Value 5</option></select>

$('#ddlSelect').prepend('<option selected=""></option>').select2({placeholder: "Select Month"});
