Dropdown Menu İssue - html

Question

I'm trying to make a header for a project. There will be dropdown menus. But there is a problem with mobile compatibility as below.
It looks like this when working beautifully above 991 pixels and below 991 pixels and this is very annoying. Can you help?
$('.main-d-l').hover(
function(){ $('.arrow').addClass('fa-rotate-270') },
function(){ $('.arrow').removeClass('fa-rotate-270') }
)
$(document).ready(function(){
// Toggle Navigation Bar
$('.hamburger-menu').click(function(){
$('.nav-btn').toggleClass("active");
$('.hamburger-menu').toggleClass("active");
});
// Toggle Dropdown Menu
$('.main-dropdown-link').click(function(){
$('.dropdown').toggleClass("active");
});
});

How can I solve this problem? In the mobile version, the dropdown part does not push other elements and stays on the side.
