The HTML <option> tag is used to define individual items in a drop-down list or a selection menu. It is typically nested within a <select> tag, enabling users to choose one or more options from a list. The <option> tag is an essential element for creating interactive forms, allowing web developers to provide users with a list of predefined choices.
The <option> tag enhances user experience by offering an intuitive way to select an item from a drop-down list. Whether it's for selecting a country, choosing a category, or setting preferences, the <option> tag is widely used in web forms and user interfaces. Additionally, the <option> tag supports multiple attributes that allow customization of each option's behavior and appearance.
Syntax of the <option> Tag
<option value="option_value">Display Text</option>
- value: This attribute defines the value that is submitted when the option is selected.
- Display Text: The visible text shown to the user in the dropdown list.
The <option> tag is typically placed inside a <select> tag, which creates the dropdown list. It can also be used inside a <datalist> tag for autocomplete suggestions.
Attributes of the <option> Tag
The <option> tag supports several attributes that provide additional functionality and customization. Here’s a breakdown of the key attributes:
| Attribute | Description |
|---|---|
| value | Specifies the value to be sent to the server when the option is selected. |
| selected | Preselects the option when the page loads. This attribute marks an option as selected by default. |
| disabled | Disables the option, making it unselectable by the user. |
| label | Provides an alternative label for the option that is visible when browsing dropdown lists. |
Using these attributes allows developers to control the behavior and usability of each option within a selection list.
Examples of HTML <option> Tag
Example 1: Basic Dropdown List
<!DOCTYPE html>
<html>
<head>
<title>Basic Dropdown List</title>
</head>
<body>
<form>
<label for="fruits">Choose a fruit:</label>
<select id="fruits" name="fruits">
<option value="apple">Apple</option>
<option value="banana">Banana</option>
<option value="orange">Orange</option>
</select>
</form>
</body>

In this example, a simple dropdown list is created with options for selecting different fruits. When a user selects an option, the corresponding value (e.g., "apple") is submitted.
Example 2: Preselected and Disabled Options
<!DOCTYPE html>

<option value="bmw">BMW</option>
<option value="audi" selected>Audi</option>
<option value="ford" disabled>Ford</option>
</select>
</form>

This example demonstrates a dropdown list where "Audi" is preselected, and "Ford" is disabled, making it unselectable by the user.
