<!DOCTYPE html> < html >
< body >
< h1 >GeeksforGeeks</ h1 >
< h2 >HTML optgroup Tag</ h2 >
< select >
<!-- optgroup tag starts -->
< optgroup label = "Programming Languages" >
< option value = "C" >
C
</ option >
< option value = "C++" >
C++
</ option >
< option value = "Java" >

</ option >
</ optgroup >
< optgroup label = "Scripting Language" >
< option value = "JavaScript" >
JavaScript
</ option >
< option value = "PHP" >
PHP
</ option >
< option value = "Shell" >

</ option >
</ optgroup >
