Tips for aligning the child elements of a dropdown menu to stick with the parent's top position

It's important that progress and my goals are clearly outlined here:

When it comes to the "Offices" section, I need the child objects to display directly below and ideally match the width of the parent element.

Here is the code snippet:

    <div class="navItem" style="display:inline">
<button class="dropbtn"> Home </button>
</div>

<div class="dropdown" style="display:inline">
<button onclick="myFunction()" class="dropbtn">Offices</button>
  <div id="myDropdown" class="dropdown-content">
    <a href="#home">Regional</a>
    <a href="#about">Global</a>
    <a href="#contact">Local</a>
  </div>
</div>

<div class="navItem" style="display:inline">
<button class="dropbtn"> Who we are</button>
</div>

<div class="navItem" style="display:inline">
<button class="dropbtn"> Contact </button>
</div>

<div class="navItem" style="display:inline">
<button class="dropbtn" id="searchBox"> Search </button>
</div>

Answer №1

Here are the modifications that were made:

The width was set to 100% (adjustable to 97 or 98 to eliminate extra padding and ensure perfect alignment with the action button), and the min-width was removed from the dropdown content.
The left property was utilized to align the dropdown relative to the parent element.
The parent div for the offices should also carry the "navItem" class as it's part of the inline buttons.

Establish the left position as zero (in relation to its parent, not the window).

To extend it to match the width of its parent, apply right: 0.

You may observe a slight 4px variance due to the inline-block on the parent. This issue can be resolved by adjusting the right position to 4px.

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');
      }
    }
  }
}

.dropbtn {
  background-color: gray;
  color: white;
  padding: 16px;
  font-size: 16px;
  border: none;
  cursor: pointer;
  width: 19.5%;
}

.dropbtn:hover,
.dropbtn:focus {
  background-color: black;
  /*invalid
  text-style: bold;*/
}

.dropdown {
  position: relative;
  display: inline-block;
}


.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f9f9f9;
  overflow: auto;
  left: 0;
  right: 4px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

.dropdown a:hover {
  background-color: #f1f1f1
}

.show {
  display: block;
}

<div class="navItem" style="display:inline">
  <button class="dropbtn"> Home </button>
</div>

<div class="dropdown" style="display:inline">
  <button onclick="myFunction()" class="dropbtn">Offices</button>
  <div id="myDropdown" class="dropdown-content">
    <a href="#home">Regional</a>
    <a href="#about">Global</a>
    <a href="#contact">Local</a>
  </div>
</div>

<div class="navItem" style="display:inline">

<div class="navItem" style="display:inline">
  <button class="dropbtn"> Contact </button>

1) The display of the parents is currently set to inline, allowing everything to align in a row.

2) By changing it to inline-block, you will notice that the drop-down now lines up properly. I recommend exploring different display types to fully grasp their behaviors, which will be beneficial to you.

3) Next, remove the width on the buttons to prevent them from being cut off. Instead, set the width on the parents and make sure the button and drop-down widths are both set to 100%. This way, they will expand to fit the full width of the parent element.

This adjustment should solve the issue at hand.
