What are the limitations of using the "size" attribute in HTML for displaying all options in a select list?

The "size" attribute in HTML only allows a fixed number of options to be displayed in a select list at a time, which can be limiting if the list contains a large number of options. To display all options without limitations, you can use a combination of CSS and JavaScript to create a custom dropdown menu that shows all options when clicked. 

<select id="custom-select" style="display: none;">
  <option value="1">Option 1</option>
  <option value="2">Option 2</option>
  <option value="3">Option 3</option>
  <!-- Add more options here -->
</select>

<div id="custom-dropdown">
  <span>Select an option</span>
  <ul>
    <li value="1">Option 1</li>
    <li value="2">Option 2</li>
    <li value="3">Option 3</li>
    <!-- Add more options here -->
  </ul>
</div>

<script>
document.getElementById("custom-dropdown").addEventListener("click", function() {
  document.getElementById("custom-select").style.display = "block";
});

document.getElementById("custom-select").addEventListener("change", function() {
  document.getElementById("custom-dropdown").querySelector("span").innerText = this.options[this.selectedIndex].text;
  this.style.display = "none";
});
</script>
