Open multiple dropdowns with the same Js function

I have these dropdowns at the left side of my page that are meant to display product details

User should be able to open them simultaneously meaning that when I open the 1st one the others are pushed down in order to be visible and be able to open too

Fiddle here https://jsfiddle.net/cazg8xwj/3/

<div class="container">
        <div class="a">
        <center>
          <div class="dropdown">
          <button onclick="myFunction()" class="dropbtn">Dropdown</button>
          <div id="myDropdown" class="dropdown-content">
              <img src="images/E11A.png" class="bottles"/>
              <img src="images/E11A.png" class="bottles"/>
          </div>
           </div>

          <button onclick="myFunction()" class="dropbtn">Dropdown</button>
          <div id="myDropdown" class="dropdown-content">
              <img src="images/E11A.png" class="bottles"/>
              <img src="images/E11A.png" class="bottles"/>
          </div>
         </div>
       </center>

     </div>

  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

.dropdown a:hover { background-color: #ddd; }

.show { display: block; }

Js

function myFunction() {
  document.getElementById("myDropdown").classList.toggle("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');
      }
    }
  }
}

when #myDropdown get class show it need to be display:inline-block instead of display:block, because you did the panel with position: absolute you have to change width to see all the content inside.

/* When the user clicks on the button,
toggle between hiding and showing the dropdown content */
function myFunction() {
  document.getElementById("myDropdown").classList.toggle("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');
      }
    }
  }
