1. Create Address Input Fields
I have created address Input Field using Boostrap 4 CDN. So, You must have its basic understanding.
Current Address Input Fields
| Input Field Name | Input Field Id |
| Address Line 1 | id=”curAddressLine1″ |
| Address Line 2 | id=”curAddressLine2″ |
| Landmark | id=”curLandmark” |
| Zip Code | id=”curZipcode” |
| City | id=”curCity” |
| State | id=”curState” |
| Country | id=”curCountry” |
Permanent Address Input Fields
| Input Field Name | Input Field Id |
| Address Line 1 | id=”pAddressLine1″ |
| Address Line 2 | id=”pAddressLine2″ |
| Landmark | id=”pLandmark” |
| Zip Code | id=”pZipcode” |
| City | id=”pCity” |
| State | id=”pState” |
| Country | id=”pCountry” |
You can use the following bootstrap code4 directory in your existing registration of your website
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">

2. Fill Current Address same as Permanent Address
You can use the following javascript code directory in your project. If you need to customize it then you can easiy do it.
In this code, I have created a custom function FillAddressInput() that is called within a checkbox so that whenever a user click the check box then It will be executed and fill the current address input field with the values of permanent address input field.
<script type="text/javascript">
function FillAddressInput()
{
let checkBox= document.getElementById('checkBox');
let pAddressLine1 = document.getElementById("pAddressLine1");
let pAddressLine2 = document.getElementById("pAddressLine2");
let pLandmark = document.getElementById("pLandmark");
let pZipcode = document.getElementById("pZipcode");
let pCity = document.getElementById("pCity");
let pState = document.getElementById("pState");
let pCountry = document.getElementById("pCountry");
let curAddressLine1 = document.getElementById("curAddressLine1");
let curAddressLine2 = document.getElementById("curAddressLine2");
let curLandmark = document.getElementById("curLandmark");
let curZipcode = document.getElementById("curZipcode");
let curCity = document.getElementById("curCity");
let curState = document.getElementById("curState");
let curCountry = document.getElementById("curCountry");
if (checkBox.checked == true)
{
let pAddressLine1Value = pAddressLine1.value;
let pAddressLine2Value = pAddressLine2.value;
let pLandmarkValue = pLandmark.value;
let pZipcodeValue = pZipcode.value;
let pCityValue = pCity.value;
let pStateValue = pState.value;
let pCountryValue = pCountry.value;
curAddressLine1.value = pAddressLine1Value;
curAddressLine2.value = pAddressLine2Value;
curLandmark.value = pLandmarkValue;
curZipcode.value = pZipcodeValue;
curCity.value = pCityValue;
curState.value = pStateValue;
curCountry.value = pCountryValue;
}
else
{
curAddressLine1.value = "";
curAddressLine2.value = "";
curLandmark.value = "";
curZipcode.value = "";
curCity.value = "";
curState.value = "";
curCountry.value = ""; }
}
</script>
