Hi guys,

Today, in this post we are create a simple salesforce lightning component to add multiple child object records to the Parent record using checkboxes. 

Prerequisites : basic understanding of Lightning Component. and Apex Programming.

For this post i take salesforce standard Account and Contact Object where as we know account is parent and contact is a child object of parent. or we can say that A single account has multiple contacts records.

After create this component we will add it to account record page layout to run it.

Demo: After add component to account record page layout
Apex Controller Class Code :


Lightning Component Code :


  • In the above lightning component, i have use 2 interface “flexipage:availableForRecordHome” and “force:hasRecordId” on line number 3.

so “flexipage:availableForRecordHome” interface used for make lightning component available for record pages. and Add the “force:hasRecordId”  interface to a Lightning component to enable the component to be assigned the ID of the currently displaying record.

force:hasRecordId” interface automatically adds an attribute named recordId to your component. This attribute is of type String, and its value is an 18-character Salesforce record ID, such as : 001xx000003DGSWAA4.

     The record ID is set only when you place the component on a lightning experience record page, or invoke it as an action from a record page.

If you don’t add “flexipage:availableForRecordHome” interface to your lightning component then your lightning component will be not available in Lightning app builder.

  • Now go back to account object and open any existing record to see the lightning component on record page layout.

  • Hi,

    Nice blog.

    Quick Suggestion : It is bind only with account and contact object. As developing with Lightning Framework, try to create components dynamically.

    In your case use sObjects to further use between any Salesforce object.

  • Nice One

    Questions:I have around more than 2000 record in contact object, at that time what i will do in this scenario.Is is possible one search button which will be help me to search record and add record .

  • Great component.

    Have made the following modification:-

    public class addChildController {
    public static List<contact> getContacts() {
    List<contact> totalList = new List<contact>();
    for(Contact cc : [SELECT Id, Name, Email FROM Contact WHERE Id NOT IN (SELECT ContactId FROM AccountContactRelation WHERE AccountId = :ApexPages.currentPage().getParameters().get(‘Id’))]){
    return totalList;

    Just can’t seem to get AccountId filter to work properly. Any suggestion would be much appreciated.

  • Hi there!

    Can I display this component on child record rather than parent? Do I need to update the code for that? I am new to Lightning Component 🙂

    Thanks for the great work!
