I'm not able to click on the dropdown options which are available in my navigation bar. I'm using bootstrap classes for creating the navigation menu. Tried some examples which are already there in google but still not getting success.

I am following a video course and did exactly as the instructor. His navbar hamburger collapses upon clicking but mine does not.
I've tried:
different browsers
rearranging the order and location of link and script tags for JQuery and bootstrap
looked through the bootstrap css file to see if there was a class attribute that was disabled
Could someone please help me out with why the hamburger button does not collapse?

I was trying to make a website using bootsrap and the menu seems to be not working (it's not clickable). I've checked the bootstrap website and there's no difference with the code I made and this. Or- I wasn't able to see it.

You should be loading jQuery first instead of bootstrap. Than it should work.
bootstrap.js needs jQuery to work.
<script src="js/jquery.js"> </script>
<script src="js/bootstrap.js"> </script>
I assume jquery.js and bootstrap.js exist in your /js/ folder.
User This code . It is working

Use the class navbar-right with the element that you are trying to align at the right side.
