Implementing Checkbox-Embedded Select Option Menus

The challenge of incorporating checkboxes within select options has long perplexed developers. While direct inclusion isn't feasible, a clever solution using HTML, CSS, and JavaScript can provide equivalent functionality.

Explanation:

1. HTML Structure: Define a multiselect div that encloses a selectBox containing the main selection and an empty overSelect for decoration. Beneath this, a hidden checkboxes div is placed to hold the individual checkboxes.
2. CSS Styling: Style the multiselect, selectBox, and checkboxes elements to create the desired aesthetics and layout. The checkboxes are initially hidden.
3. JavaScript Function: Implement a JavaScript function that toggles the checkboxes' visibility based on the click of the selectBox.

Code Snippet:

<form>
  <div class="multiselect">
    <div class="selectBox" onclick="showCheckboxes()">
      <select>
        <option>Select an option</option>
      </select>
      <div class="overSelect"></div>
    </div>
    <div>

By following these steps, you can achieve the desired functionality of checkboxes embedded within select options, providing users with an enhanced and more intuitive interaction.
