A collection of useful plugins that do additional jobs
FormValidation comes with various built-in plugins listed in alphabetical order, split into two groups as follows:

Core plugins

These plugins are often used and included in the bundle/popular(.min).js file. You don't need to include any external plugin files to use them.

External plugins

You don't need all external plugins most of the time. So, you have to include them right after the bundle/popular(.min).js file on your page.
<script src="/vendors/@form-validation/umd/bundle/popular.min.js"></script>
You need to insert external plugins (Bootstrap in this case) after `bundle/popular.min.js`
<script src="/vendors/@form-validation/umd/plugin-bootstrap/index.min.js"></script>
