HTML - <optgroup> Tag

An HTML tag called <optgroup> is used in the <select> element to group together relevant <option> elements. It offers a method for setting up and structuring the choices in a dropdown list. This can be very helpful when you wish to organize and improve user experience by categorizing a big list of options into parts or categories.

<optgroup label= "..."></optgroup>

Example

In the following program, we are using the HTML <optgroup> tag to create a single group of options with the "select" element in an HTML.

<!DOCTYPE html>
<html lang="en">
<head>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>HTML optgroup tag</title>
</head>
<body>
   <!--create optgroup tag-->
   <select>
      <optgroup label='Fruits'>
         <option value="apple">Apple</option>
         <option value="banana">Banana</option>
         <option value="orange">Orange</option>
         <option value="grapes">Grapes</option>
      </optgroup>
   </select>
</body>
</html>

When we run the above code, it will generate an output consisting of the dropdown menu displayed with a default value displayed on the webpage.

Example

Following is another example of the HTML <optgroup> tag. Here, we are using the <optgroup> tag to create multiple groups of options within the "select" element in an HTML.

<!DOCTYPE html>
<html lang="en">
<head>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>HTML optgroup tag</title>
</head>
<body>
   <!--create optgroup tag-->
   <select>
      <option value="">Choose your option</option>
      <optgroup label='States'>
         <option value="uttarpradesh">Uttar Pradesh</option>
         <option value="punjab">Punjab</option>
         <option value="bihar">Bihar</option>
         <option value="jharkhand">Jharkhand</option>
      </optgroup>
      <optgroup label='Related Cities'>
         <option value="lucknow">Lucknow</option>
         <option value="jalandhar">Jalandhar</option>
         <option value="patna">Patna</option>
         <option value="ranchi">Ranchi</option>
      </optgroup>
   </select>
</body>
</html>

On running the above code, the output window will pop up, dispaying the dropdown menu with different select option on the webpage.

Example

In this example, we are using the HTML <optgroup> to create a grouping option within the "select" element in an HTML. We use the "disabled" attribute to disable the created group. 

<!DOCTYPE html>
<html lang="en">
<head>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>HTML optgroup tag</title>
</head>
<body>
   <!--create optgroup tag-->
   <select>
      <option value="">Choose your option</option>
      <optgroup label='Group 1'>
         <option value="opt1.1">Option 1.1</option>
         <option value="opt1.2">Option 1.2</option>
      </optgroup>
      <optgroup label='Group 2'>
         <option value="opt2.1">Option 2.1</option>
         <option value="opt2.2">Option 2.2</option>
         </optgroup>
         <optgroup label='Group 3' disabled>
         <option value="opt3.1">Option 3.1</option>
         <option value="opt3.2">Option 3.2</option>
      </optgroup>
   </select>
</body>
</html>

When we run the above code, it will generate an output consisting of the dropdowm menu where some are used with disabled attribute displayed on the webpage.

Example

Following is the example, where we are creating a grouping of options within the "select" element using the HTML <optgroup> tag in an HTML. We use CSS to style the "optgroup". 

<!DOCTYPE html>
<html lang="en">
<head>
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>HTML optgroup tag</title>
   <style>
      optgroup {
         color: green;
         background-color: aquamarine;
      }
   </style>
</head>
<body>
   <!--create optgroup tag-->
   <select>
      <option value="">Choose your option</option>
      <optgroup label='Frontend'>
         <option value="html">HTML</option>
         <option value="css">CSS</option>
         <option value="javascript">JavaScript</option>
      </optgroup>
         <optgroup label='Backend'>
         <option value="java">Java</option>
         <option value="php.2">PHP</option>
      </optgroup>
   </select>
</body>
</html>

On running the above code, the output window will pop up displaying the drop down menu applied with a CSS on the webpage.
