Hello Everyone, In this tutorial, I am going to provide an example of Lightning Component that illustrates you, how to bind a picklist field value dynamically in Lightning Component. In this example, I am using Schema namespace to get sObject field value dynamically, so please go through the tutorial.

After completing this tutorial, you’ll able to:
  • Bind Picklist field value dynamically.
So, Let's get started,

Dynamically Bind Picklist Value in Lightning Component

Step 1: Login to your Salesforce Org. and open developer console.


Step 2: Go to File>New>Apex Class and Create an Apex controller called PickListHandler. Replace following code in apex controller.

 PickListHandler.apxc
 public class PickListHandler {    
    @AuraEnabled
    public static List<String> getIndustry(){
        List<String> lstndustry=new List<String>();
        Schema.DescribeFieldResult fieldResult = Account.Industry.getDescribe();
        List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
        for(Schema.PicklistEntry s:ple){                
            lstndustry.add(s.getLabel());                
        } 
        return lstndustry;
    }     
 }
Step 3: Go to File>New>Lightning Component and create a Lightning Component called PickList. Replace the following markup in the Lightning Component.

 PickList.cmp 
 <aura:component controller="PickListHandler">    
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />
    <aura:attribute name="lstIndustry" type="String[]" />
    <ui:inputSelect aura:id="ddIndustry" change="{!c.getSelectedValue}">
        <ui:inputSelectOption label="-Select-" value="true"/>        
        <aura:iteration items="{!v.lstIndustry}" var="value">           
            <ui:inputSelectOption label="{!value}" text="{!value}" />
        </aura:iteration>
    </ui:inputSelect>
 </aura:component>
PickListController.js 
  ({
    doInit : function(component, event, helper) {
        var action = component.get("c.getIndustry");
        action.setCallback(this, function(e) {
            if(e.getState()=='SUCCESS'){
                var result=e.getReturnValue(); 
                component.set("v.lstIndustry",result);
            }
        });
        $A.enqueueAction(action);
    },
    
    getSelectedValue:function(component, event, helper){
        var picklist=component.find('ddIndustry');
        var picklistvalue=picklist.get('v.value');
        alert(picklistvalue);
    },
 })
Step 4: Go to File>New>Lightning Application and create a Lightning Application called Preview. Replace the following markup in the Lightning Application and click on the preview button. 
 <aura:application extends="force:slds"> 
    <c:PickList/>
 </aura:application>
