HTML Select List Option

Introduction

The HTML <option> tag is used to define the options in a drop-down list in an HTML form. It is attached to the <select> tag and its variants such as <datalist> and <optgroup>. This tag helps users make a selection from a list of choices. This lab will guide you through the steps to implement an HTML drop-down list using the <option> tag.

Create a element

Create an HTML file named index.html in your preferred text editor.

Start by creating a basic HTML form:

<form></form>

Create a element and add options

Inside the <form> element, add a <select> element, which will create a drop-down list.

<form>
  <select>
    <option value="option1">Option 1</option>
    <option value="option2">Option 2</option>
    <option value="option3">Option 3</option>
  </select>
</form>

Here, we have added three <option> tags inside the <select> tags with the value attribute set to "option1", "option2", and "option3".

Add a prompt

Let's add a prompt text. Inside the <select> tag, add the following code:

<select>
  <option value="" disabled selected>Select an option</option>
  <option value="option1">Option 1</option>
  <option value="option2">Option 2</option>
  <option value="option3">Option 3</option>
</select>

Here, we have added a new <option> tag with the following attributes:

• value="" which sets the value to an empty string.
• disabled which disables the option from being selected.
• selected which is used to indicate the default choice for the drop-down list.
• The text inside the <option> tag which acts as a prompt.

Add a submit button

We need a submit button to submit the form. Add the following code after the <select> tag:

<form>
  <select>
    <option value="" disabled selected>Select an option</option>
    <option value="option1">Option 1</option>
    <option value="option2">Option 2</option>
    <option value="option3">Option 3</option>
  </select>

  <br /><br />

  <input type="submit" value="Submit" />
</form>

Save the file and run it in a web browser to see the drop-down list in action.

Summary

In this lab, we learned how to use the HTML <option> tag to create a drop-down list. We started by creating an HTML form, then added a <select> element, added options inside it with the value attribute, and added a prompt text. Finally, we added a submit button to submit the form. The <option> tag plays a crucial role in creating dynamic HTML forms.
