Oracle ADF: Need to show checkbox before label using selectBooleanCheckbox

I was trying to show checkbox before label using selectBooleanCheckbox in oracle ADF but it is showing checkbox after label.

<af:panelFormLayout id="pfl2" maxColumns="4" rows="1">  
  <af:iterator id="i2" value="#{pageFlowScope.StoreSearchMB.storeCreateCheckboxes}" var="List">
     <af:selectBooleanCheckbox label="#{List.VStore}" id="sbc2" inlineStyle="Color:#949595;font-size:18px;" value="#{List.VStStatus}"/>
  </af:iterator>
</af:panelFormLayout>

Could you please help me to get the correct way?
