I am making a website about trains and I want to make a version for desktop and tablet. In the tablet version I want to hide the navigation bar and make it into a dropdown menu and I have done it but I cant put it right underneath the top bar. Even if i put the position absolute and the top value to be the height of the top bar its still doesnt work and when i resize it it always changes the position of the menu. Like if i fine tune it for one pixel size screen the moment i resize to test it just isnt placed in the right spot again.
function TrainDropdown() {
const trainMenu = document.getElementById("trains");
trainMenu.classList.toggle("show");
console.log("TrainDropdown toggled:", trainMenu.classList.contains("show"));
}
function Menu() {
const navBar = document.getElementById("phone-nav-bar");
navBar.classList.toggle("show-nav-bar");
}
function MobileTrainDropdown() {
const trainElements = document.getElementById("tablet-trains");
if (trainElements.style.display === "none") {
trainElements.style.display = "flex";
} else {
trainElements.style.display = "none";
}
}
window.addEventListener("click", function (event) {
console.log("Window click detected on:", event.target);
// Close train dropdown if clicked outside the dropdown button
if (!event.target.closest('.dropdown-button')) {
const dropdowns = document.getElementsByClassName("train-elements");
for (let i = 0; i < dropdowns.length; i++) {
const openDropdown = dropdowns[i];
if (openDropdown.classList.contains('show')) {
openDropdown.classList.remove('show');
console.log("Closed train dropdown:", openDropdown);
}
}
}
// Close mobile nav menu if clicked outside menu button and nav bar
const navBar = document.getElementById("phone-nav-bar");
const menuButton = document.querySelector('.menu-button');
if (navBar && menuButton && !menuButton.contains(event.target) && !navBar.contains(event.target)) {
navBar.classList.remove("show-nav-bar");
console.log("Closed mobile nav menu.");
}
