I'm trying to use standalone selectize library in my webapplication. But getting this error

Uncaught TypeError: $(...).selectize is not a function

Here is my code: In header

<script type="text/javascript" src=".4.0/jquery.min.js"></script>
<script type="text/javascript" src="../js/selectize.min.js" charset="utf-8"></script>
<link rel="stylesheet" type="text/css" href="../css/selectize.default.css" >

In the html file

<label for="input-tags3">Skills</label>
<input id="input-tags3" name="skills" type="text" th:field="*{skills}" class="demo-default selectized text-input" value="science,biology,chemistry" tabindex="-1" style="display: none;">
<div class="selectize-control demo-default multi plugin-remove_button">
    <div class="selectize-input items not-full has-options has-items">
    <div class="item" data-value="science">science<a href="javascript:void(0)" class="remove" tabindex="-1" title="Remove">×</a></div>

    <div class="selectize-dropdown multi demo-default plugin-remove_button" style="display: none; width: 520px; top: 36px; left: 0px; visibility: visible;">
    <div class="selectize-dropdown-content">
    <div class="option" data-selectable="" data-value="physics">physics</div>
    </div>
   </div>
 </div>

In the js file

$('#input-tags3').selectize({
    plugins: ['remove_button'],
    delimiter: ',',
    persist: false,
    create: function(input) {
        return {
            value: input,
            text: input
        }
    }
});

What's missing?

• javascript
• jquery
• html
• selectize.js

• Are you including jQuery? Where do you define options? – Tyler Roper Commented Jun 24, 2019 at 1:28
• Yes, I've added <script type="text/javascript" src="ajax.googleapis./ajax/libs/jquery/3.4.0/…> – Ima Miri Commented Jun 24, 2019 at 1:29
• Before selectize? And where do you define options? EDIT: Per your edit: jQuery must be included before any jQuery plugins. You're currently including selectize before jQuery. EDIT 2: Can you please copy + paste your actual code? It's hard to know what your mistake is if you continuously edit them out. – Tyler Roper Commented Jun 24, 2019 at 1:30
• I updated it, it's before selectize. – Ima Miri Commented Jun 24, 2019 at 1:32
• @TylerRoper sorry about that. last update is correct – Ima Miri Commented Jun 24, 2019 at 1:35

You should wrap $('select').selectize(); by $(function() {}) as follows in order to initialize jQuery prototype.

<script type="text/javascript" src="selectize.js"></script>
<link rel="stylesheet" type="text/css" href="selectize.css" />
<script>
$(function() {
    $('select').selectize(options);
});
</script>

Refer here to get details.

PS: For options, you could refer to the following examples:

• Doc https://github./selectize/selectize.js/blob/master/docs/usage.md#configuration
• Example https://github./selectize/selectize.js/blob/master/examples/cities.html

...
$select_city = $('#select-city').selectize({
  valueField: 'name',
  labelField: 'name',
  searchField: ['name']
});
select_city = $select_city[0].selectize;
...
select_city.disable();
...

The issue fixed after adding the jquery at the beginning of the document.ready function.

$(document).ready(function(){
$('#input-tags3').selectize({
    plugins: ['remove_button'],
    delimiter: ',',
    persist: false,
    create: function(input) {
        return {
            value: input,
            text: input
        }
    }
});
....
});
