Hi Guys!
I want to show on my component a Checkbox Group. The values are already defined by the Record. My code, for now, is this one with all the picklists that work perfectly -
How I can add those 4 checkboxes?


<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" >

           <lightning:layout multipleRows="true">
          <lightning:layoutItem size="6">
       <lightning:recordForm recordId="{!v.recordId}" objectApiName="Lead" fields="My_Commodity_Interests_include__c" />
       </lightning:layoutItem>
           <lightning:layoutItem size="6">     
               <lightning:recordForm recordId="{!v.recordId}" objectApiName="Lead" fields="Non_Ferrous_Metals__c"/>
</lightning:layoutItem>
       <lightning:layoutItem size="6">
