Having trouble with the javascript dropdown functionality

I am currently facing an issue with my Javascript menu. The hover and click functionality for the main menu items is working perfectly fine, but I am struggling to make the dropdown feature work.

Here is the code snippet from menu.js:

 /* When the user clicks on the button,
     toggle between hiding and showing the dropdown content */
 function myFunction() {
   //document.getElementById("myDropdown").classList.toggle("show");
   //document.getElementsByClassName("dropdown-content").show);
   //document.getElementById("pmd").classList.toggle("show");
   pmd.show;
 }
 }
 // Close the dropdown if the user clicks outside of it
 window.onclick = function(event) {
   if(!event.target.matches('.dropbtn')) {
     var dropdowns = document.getElementsByClassName("dropdown-content");
     var i;
     for(i = 0; i < dropdowns.length; i++) {
       var openDropdown = dropdowns[i];
       if(openDropdown.classList.contains('show')) {
         openDropdown.classList.remove('show');
       }
     }
   }
   if(!event.target.matches('.dropbtnpm')) {
     var dropdowns = document.getElementsByClassName("dropdown-content");
     var i;
     for(i = 0; i < dropdowns.length; i++) {
       var openDropdown = dropdowns[i];
       //if (openDropdown.classList.contains('show')) {
       openDropdown.classList.remove('show');
     }
   }
 }

Below is the HTML code snippet for the menu where I want to implement a dropdown. Currently, I'm just trying to display the text "test" to check functionality:

 <td><button onmouseover="myFunction();"
 onclick="location.href='property-mngt.html';" value="Property Management"
 class="dropbtn">PROPERTY MANAGEMENT</button>
<div id="pmd" class="dropdown-content"> test </div>
 </td>

The CSS styles are as follows:

.dropbtn {
  border:  none;
  padding: 16px;
  cursor: pointer;
  background-color: #ffffff;
  color: black;
  height: 125px;
  min-height: 125px;
  font-size: 12px;
}
/* Additional CSS styles omitted for brevity */

My objective is to have the dropdown list appear when hovering over the specific menu item. Despite trying different approaches like changing the class in the HTML, such as

<div id="pmd" class="dropdown-content.show"> test </div>
, 'test' only displays on the menu without the dropdown functionality.

I seem to be stuck on how to trigger the dropdown to show up upon hovering over that particular menu item. Any insights or suggestions would be greatly appreciated!

Answer №1

If you want to showcase multiple elements, make sure to select the first one and present it accurately.

document.getElementsByClassName('dropdown-content')[0].style.display = 'block'

Alternatively, you can utilize

document.querySelector('dropdown-content')
