Bootstrap5-Toggler Button-CodePudding

I have used the toggler button using bootstrap 5 in the navbar but it is not displaying the navbar items that are collapsed on minimizing browser screen. Why is it not working properly? and how to resolve it?

The code you provided works fine for me. Are you sure you included the Bootstrap JS file?

You are missing a bootstrap JS CDN link, Add this inside your head element
