we select in user lookup can only edit/change values from 2nd and 3rd field

Create 3 fields on VF page. One is lookup to user, 2nd is picklist and 3rd one is text field

Now, we need to implement the functionality like as below

The person that we select in user lookup can only edit/change values from 2nd and 3rd field. In case of other user, other than selected user in user lookup, user cannot change the value. Instead it will come as readonly

Hi Manoj,

Please use below code: 
<apex:page standardController="Account">
    <apex:form >
        <apex:pageBlock >
            <apex:pageblockSection >
                <apex:outputField value="{!Account.Custom_Owner__c}"  />
            </apex:pageblockSection>
            
            
        </apex:pageBlock>
        <apex:pageBlock >
            <apex:pageblockSection rendered="{!Account.Custom_Owner__c = $User.Id}" >
                <apex:outputField value="{!Account.Name}" />
                <apex:outputField value="{!Account.AccountNumber}" />
            </apex:pageblockSection>
            
            <apex:pageblockSection rendered="{!Account.Custom_Owner__c != $User.Id}">
                <apex:outputField value="{!Account.Name}" html-disabled="true"/>
                <apex:outputField value="{!Account.AccountNumber}" html-disabled="true"/>
            </apex:pageblockSection>
        </apex:pageBlock>
    </apex:form>  
</apex:page>

Please let me know if helped.

Thnx Ramakant , but Actually we dont want use 3rd PageBlockSection cuz the fields are repeated again in the code.so is it possible only using 2nd PageBlockSection.
