JavaScript and Responsive Design Techniques

I'm struggling to create a responsive page that starts with a mobile-first approach, but I keep running into the same issue.

When I have my dropdown menu in the mobile version, it looks good. However, when I try to switch it to the non-mobile version, it doesn't work. I want a mobile version with one column and then switch to two columns when the window size exceeds 400px.

After numerous changes, this is what my current code looks like:

$('.slide ul').slideUp();

var windowSize;
windowSize = $('.wrapper').width();
$(window).on('load', checkSize());

$(window).resize(checkSize());


function checkSize(e) {
    if (windowSize < 400) {
        mobile();     
    } else if (windowSize > 400) {
        noMobile();
    }
}


function mobile(e){
    $('.especial').hide();      
    $('.toggle').on('click', toggleMenu);  

}

function toggleMenu(e){
    $('.slide ul').slideToggle();
    e.preventDefault(); 
}

function noMobile(e){
    $('.lista').show();

    var selectedList;
    selectedList = $('.elegidos').html();
    $('.especial').prepend(selectedList);     
}

Thank you for your help!

One way to handle this is utilizing CSS media queries:

@media (max-width: 400px) {
  .list {
    display: block;
  }
  .special {
    display: none;
  }
}

@media (min-width: 401px) {
  .list {
    display: none;
  }
  .special {
    display: block;
  }
}
