Hello Friends, In this post, I am going to present an example to set the default value in picklist (ui:inputSelect) in Lightning Component.

After completing this unit you’ll able to:
  • Set default value of picklist lightning component. 
Lightning Component:
 <aura:component>
    <ui:inputSelect aura:Id="ddlPick" multiple="false" label="Select Color">
        <ui:inputSelectOption label="Red" text="Red" value="true"/>
        <ui:inputSelectOption label="Green" text="Green"/>
        <ui:inputSelectOption label="Yellow" text="Yellow"/>
        <ui:inputSelectOption label="Black" text="Black"/>
        <ui:inputSelectOption label="Blue" text="Blue"/>
    </ui:inputSelect>
 </aura:component>
In the above example, when you set value property of <ui:inputSelectOption> is true, It become the default selected value of <ui:inputSelect> lightning component.
