I am using lightning:combobox seems like required doesn't work, can someone please help me with the code. How can I make this lightning:combobox field required by throwing some validation using client side controller in Lightning Aura
#Aura Component #Aura #Aura Lightning Components #Lightning Aura #Lightning Aura Component
When I pressed the submit button, I was launching handleChange2 with validity2 set to true on the parent component using this custom component.
the custom component that includes lightning: combobox.
cmp
<aura:attribute name="validity2" type="Boolean" default="false"/>
<aura:handler name="change" value="{!v.validity2}" action="{!c.handleChange2}"/>
controller
handleChange2 : function(component, event, helper) {
var inputCmp = component.find("required_ck");//Aura: id for lightning: combobox
inputCmp.showHelpMessageIfInvalid();
},
