Hi I’m new to the web development and programming. Currently I’m creating my first website with using HTML,CSS and Bootstrap. I want to create menu bar for only showing to the mobile users. I used bootrap 5 version for that. But my tooggler dropdown menu doesn’t show up in the screen when click the hamburger icon. Can you guys help me to fix this problem.
