My select2 is not working. It just shows up with multiple selectbox
<form action="">
<select class="js-example-basic-multiple" multiple="multiple">

<option value="CA">California</option>

<option value="UT">Utah</option>
<option value="WY">Wyoming</option>
</select>
</form>
<script type="text/javascript">
$(".js-example-basic-multiple").select2();
</script>
Error in console:
Uncaught TypeError: $(...).select2 is not a function

This runs fine if you have imported correctly - jQuery library, select2 js and select2 css.
Here I have imported jquery 2.0.0 and select2 css and js from their cdn and it works fine:
$(".js-example-basic-multiple").select2();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.min.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/select2.min.js"></script>
<form action="">
<select class="js-example-basic-multiple" multiple="multiple">
<option value="AK">Alaska</option>
<option value="HI">Hawaii</option>
<option value="CA">California</option>
<option value="NV">Nevada</option>
<option value="OR">Oregon</option>
<option value="WA">Washington</option>
<option value="AZ">Arizona</option>
<option value="CO">Colorado</option>
<option value="ID">Idaho</option>
<option value="MT">Montana</option>
<option value="NE">Nebraska</option>
<option value="NM">New Mexico</option>
<option value="ND">North Dakota</option>
<option value="UT">Utah</option>
<option value="WY">Wyoming</option>
</select>
</form>
Note:
You need to execute your select2 initialisation code only after you have included both the js libraries and DOM has loaded, which is a general practice for most jQuery plugins, not only this. So, while using this code you should write this script after including jquery and select2 scripts:
<script>
$(document).ready(function(){
$(".js-example-basic-multiple").select2();
});//document ready
</script>

I've been using this custom Bootstrap select plugin BSMultiselect. I need to select some options after the page has already been loaded, using jQuery/Javascript.
The API documentation is not very clear how to do this. What I've tried is:
var bsMultiSelect = $('#facilityFilter').BsMultiSelect();
bsMultiSelect.updateOptionSelected(0);
This effectively does nothing.
In order to select an option you need for the first set the selected attribute before you update the bsMultiSelect.
The snippet:
$(function () {
var $multiSelects = $("select[multiple='multiple']");
$multiSelects.bsMultiSelect();
// set the selected attribute...
$multiSelects.find('option').eq(0).prop('selected', 'selected');
// ....so, update the bsMultiSelect
$multiSelects.data('DashboardCode.BsMultiSelect').updateOptionSelected(0);
});
.row {
background: #f8f9fa;
margin-top: 20px;
}
.col {
border: solid 1px #6c757d;
padding: 10px;

I tried to add a CSS Class to the Dropdown, but it is resulting in a Console Error.
Uncaught Error: No select2/compat/dropdownCss
$('.myfilter').select2({
placeholder: name,
allowClear: true,
dropdownCssClass: "mytestdropdown",
});
What I try to achieve is to add a Class to the Dropdown, so I can style the Dropdown-Elements of one Dropdown with CSS (Instead of just styling all Select2 Dropdowns all over the Website!)
select2 is depended on the version of select2 that you are using. The HTML structure changed in one of the versions.
$(".jSelectbox").select2();
And put 'error' class on the select box.
.error + .select2-container,
.error + .select2-container + .select2-container .select2-dropdown {
border: 3px solid red !important;
}
$(".jSelectbox").select2();
.error + .select2-container,
.error + .select2-container + .select2-container .select2-dropdown {
border: 3px solid red !important;
}

It turned out that there are 2 select2 files:
select2.js
ans select2.full.js
For my purpose one would need the select2.full.js - otherwise the options dropdownCssClass and containerCssClass are not working.
I used select2.js(3.4.5) for my previous project and now I need to make some changes into it. it's not possible to upgrade version of select2 now.
I need to change the background color of a select2 search box, I tried it but I can't please see my fiddle or snippet. I want background-color:red after user select option from select box.
I try to apply CSS all the elements using jquery
$('.select2-choices').attr("style",'background-color:#EA4335 !important');
$('.select2-choices > *').attr("style",'background-color:#EA4335 !important');
you can see in my code also.

I'm trying to re-create the most basic "states" select2 example, but it does not match beyond the first letter - just like a normal select element. It does seem to be loading select2, for example, it displays the selected value to the right of the select element. However, when I try to type a state, it only seems to match the first character. I.e., If I type "t" it will match "Texas", but typing "dak" will match "Delaware" rather than "North Dakota".
I've create a gist of my complete html page. I copied the select element directly from the example page, so there's not a whole lot to it.
In a nutshell, I create a select element with the class js-example-basic-single, and then I call select2() on that element.
<script type="text/javascript">
$(document).ready(function() {
$(".js-example-basic-single").select2();
});
</script>
Edit: On JS Bin
Updated jsBin.
Check the simple working snippet below based on you gist code, and make sure you're adding the CSS link include :
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.min.css" rel="stylesheet"/>
Hope this helps.
$(document).ready(function() {
$(".js-example-basic-single").select2({width:'100%'});

I am working with the Semantic UI searchable dropdown, which if you're not familiar with it, it can be found here: http://semantic-ui.com/modules/dropdown.html#search-selection.
How would I make it so that once an item is selected in the dropdown, that when you click out and click back in, it would show the currently selected item at the top of the list? So scroll to the selected/active item?
What version of Semantic UI you're using? 'Cause the default behavior of Semantic UI search selection dropdown is just fine.
$('.ui.search.dropdown').dropdown();
