I am facing an issue with a dropdown menu in my webpage. The menu is initially hidden, but should become visible when the list element containing it is clicked. I have written JavaScript code to add a class that changes the visibility property to visible upon clicking. However, the problem I encountered is that the visibility only changes for a brief moment and then reverts back to hidden. How can I modify the code so that the dropdown menu remains visible after the initial click until the next one?
document.querySelector('#drop').addEventListener('click', (e) => {
document.querySelector('.sub-men').classList.toggle('visible');
})
