Lightning Component For Custom RecordType Selection

Apex Controller:

Here, we are getting List of RecordTpes from Account Object.

public class RecordTypeSelectorController {
 
    @AuraEnabled
    public static List<RecordType> getListOfRecordType(){
        String query = 'SELECT Id,Name FROM RecordType WHERE SobjectType =\''+'Account'+'\' ';
        List<RecordType> rtNames = new List<RecordType>();
        Schema.SObjectType  objType = Account.SObjectType;     
        for(RecordTypeInfo rt : objType.getDescribe().getRecordTypeInfos()){
            System.debug('rt.getName()'+rt.getName());
            rtNames.add(new RecordType(Id = rt.getRecordTypeId(),Name = rt.getName()));
            System.debug('rtNames'+rtNames);
        } 
        return rtNames; 
    }
}


Lightning Component:

<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes" controller="RecordTypeSelectorController" access="global">
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" access="public"/>
    <aura:attribute name="recordTypes" type="String[]" access="public"/>
    <div class="slds">
        <div class="demo-only" style="height: 640px;" id="newClientSectionId">
            <section role="dialog" tabindex="-1" aria-labelledby="modal-heading-01" aria-modal="true" aria-describedby="modal-content-id-1" class="slds-modal slds-fade-in-open">

                                <input type="radio" value="{!rt.Name}" name="recordTypeRadio" id="{!rt.Id}" style="margin-right: 5px;" />{!rt.Name}
                            </ol> 
                        </aura:iteration>
                    </div>
                    <footer class="slds-modal__footer">
                        <button class="slds-button slds-button_brand" onclick="{!c.createRecordFun}">Next</button>

                </div>
            </section>
            <div class="slds-backdrop slds-backdrop_open"></div>

    </div>

</aura:component>

JavaScript Controller:

Here, we are using force:createRecord event. This event tells app to use standared create record page.

({
    createRecordFun : function (component, event, helper) {
        var rtDet = document.querySelector('input[name="recordTypeRadio"]:checked');
        if(rtDet != null) {
            document.getElementById("newClientSectionId").style.display = "none" ;
            var createRecordEvent = $A.get("e.force:createRecord");
            createRecordEvent.setParams({
                "entityApiName": "Account",
                "recordTypeId":rtDet.id
            });
            createRecordEvent.fire();
        } 
    },
    doInit : function(component, event, helper) { 
        helper.RecordTypeSelectorController(component); 
    }

})

JavaScript Helper:

({
   RecordTypeSelectorController: function(component) {
    var action = component.get("c.getListOfRecordType");
    action.setCallback(this, function(actionResult) {
        var infos = actionResult.getReturnValue();
        component.set("v.recordTypes", infos);
    });
    $A.enqueueAction(action);
  }

})

Note :

This force:createRecord event is handled by the one.app container.It's supported in Lightning Experience and salesforce1 only.This event presents a standard page to create a record.
