Dropdown menus are a common feature in web forms, allowing users to choose one option from a predefined list. In HTML, dropdowns are created using the <select> element in combination with <option> elements. This article will explain how to create dropdown menus with these elements, complete with code examples and visible outputs.
The <select> Element
The <select> element is used to create a dropdown menu. It acts as a container for multiple <option> elements, each representing a different choice.
The <option> Element
The <option> element defines an individual option within a dropdown menu. Users can select one of these options when interacting with the form.
Basic Dropdown Example
Let's start with a simple example of a dropdown menu where users can select their favorite fruit:

<body>
<h2>Favorite Fruit</h2>
<form>
<label for="fruit">Choose a fruit:</label>
<select id="fruit" name="fruit">
<option value="apple">Apple</option>
<option value="banana">Banana</option>
<option value="cherry">Cherry</option>
<option value="date">Date</option>
</select>
<button type="submit">Submit</button>
</form>
</body>
</html>
Output:
Adding a Default Option
You can add a default option that prompts users to make a selection. This can be useful for forms where an option must be selected.

<h2>Favorite Fruit</h2>
<form>
<label for="fruit">Choose a fruit:</label>

<option value="cherry">Cherry</option>
<option value="date">Date</option>
</select>
<button type="submit">Submit</button>
</form>
</body>
</html>

Grouping Options with <optgroup>
You can group related options together using the <optgroup> element. This is particularly useful for large dropdown menus where categorizing options can improve usability.
