HTML DOM Select remove() Method
The HTML DOM select remove() method removes a new option from a drop-down list in an HTML document.
Syntax
Following is the syntax −
object.remove(index)
Here, index represents the index of the option which is to be removed from the drop-down list.
Example
Let us see an example of HTML DOM select remove() method −
<!DOCTYPE html>
<html>
<head>
<style>
html{
height:100%;
}
body{
text-align:center;
color:#fff;
background: radial-gradient( circle farthest-corner at 23.1% 64.6%, rgba(129,125,254,1) 0%, rgba(111,167,254,1) 90% ) no-repeat;
height:100%;
}
p{
font-weight:700;
font-size:1.1rem;
}
.drop-down{
display:block;
width:35%;
border:2px solid #fff;
font-weight:bold;
padding:2px;
margin:1rem auto;
