Implementing the Behavior of Dropdown Menu
Explore how to create interactive dropdown menus by toggling submenu visibility on hover, managing the active menu item state, and properly handling mouse events using plain JavaScript. Learn to bind event handlers correctly and control display properties to build a responsive, usable dropdown component.
We'll cover the following...
Toggling submenu visibility #
First thing’s first: the submenu shouldn’t be visible when a menu item isn’t hovered over. Let’s set the display: none property to be the default state, and when a menu item is hovered, it toggles back to display: block.
We’ll find all the elements that are of the class name menu__main__item, and iterate through them so that we can bind functions to events. When one of these items get the event onmouseenter triggered, the function menuItemEnter is called. menuItemEnter finds the submenu by the class name, and sets the display property.
