In this blog, we will discuss how to Add Delete Row Dynamically In Salesforce Lightning Component. We shall take an example of adding account records in Salesforce using Add Delete Row functionality.
Similarly, we have created 1 sample lightning component using which user can create multiple records as per requirement by Adding or Deleting new rows on UI. Also make ‘Account Name’ as mandatory field.
- Step 1: Go to the Developer Console ->> File ->> New ->> Apex Class: AuraController.apxc
- Create apex class i.e. AuraController
- Create AuraEnabled method i.e. saveAccountList which take single parameter to hold account list. Refer below code snippet.
public class AuraController
{
@AuraEnabled
public static void saveAccountList(List<Account> accList)
{
Insert accList;
}
}- Step 2: Go to the Developer Console ->> File ->> New ->> Lightning Component: AuraComponent.cmp
- Declare attribute of type account array to store multiple account and name it as ‘accountList’.

<aura:attribute name="accountList" type="Account[]"/>
