I have a VF page where I am trying to set up a rerender of 1 field when a certain set of values is selected in another field (picklist). I can do the rerender on the entire pageBlockSection, but I would like to only rerender the 2 elements involved, which are contained in 2 separate pageBlockSectionItems. Does anyone know how I can accomplish this? Below are the 2 sections I would like to rerender.
<apex:pageBlock mode="edit" title="Required Fields on Account">
<apex:pageBlockSection columns="1">
<apex:pageBlockSectionItem id="Vertical">
<apex:outputLabel value="Buyer Segment"/>
<apex:actionRegion >
<apex:inputField value="{!Account.Buyer_Segment__c}">
<apex:actionSupport event="onchange" reRender="Vertical"/>
</apex:inputField>
</apex:actionRegion >
</apex:pageBlockSectionItem>
<apex:pageBlockSectionItem rendered="{!IF(Account.Buyer_Segment__c = $Label.Acct_BuySeg1,TRUE,FALSE)}">
<apex:outputLabel value="Vertical"/>
<apex:inputField value="{!Account.Industry}" />
</apex:pageBlockSectionItem>
...Other pageBlockSectionItems here...
</apex:pageBlockSection>
<apex:pageBlock>
