navbar without toggle bootstrap 4 code example

Example: navbar toggle not working bootstrap 4

You need to put:-

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
Before all the other js files.

Then it will work.

Note:- Take care that jQuery core-library/base-library need to be added first and then only any other jQuery file/library can be added
