How Can I Make a Dropdown Menu Toggle Work on Both Mouse and Touch Devices?

Document .click Function for Touch Devices

In order to toggle a dropdown menu on a touch device, we can use the .on() event handler to listen for both click and touch events on the document. The updated code:

$(document).on('click touchstart', function() {

  if ( $(".children").is(":visible")) {
    $("ul.children").slideUp('slow');
  }

});

Here's why this works:

Click Event:
The click event is typically triggered by a mouse click, but modern browsers also fire this event for a tap on a touch screen.

touchstart Event:
The touchstart event is fired as soon as an element is touched, ensuring that the function is triggered even on devices that may not support the standard click event for touch input.

By using the .on() event handler with both 'click' and 'touchstart' events, we ensure that the function will be executed regardless of the input method (either mouse click or touch). This allows users to toggle the dropdown menu consistently across both desktop and touch devices.
