Don't reload to top of the page

Hello everyone, I have a problem that it is driving me crazy. I have radio buttons on my Visualforce page, some of the radio buttons are hidden when you first open the page, but if let's say the radio button #10 is changed to the option 'Yes', I refresh the page and show 2 more radio buttons.

My problem is that it's always reloading the page to the top and I don't want it.
I have this radio buttons inside pageblock and outputpanel.
I was able to make it work to go to a button but not a radio button.

On Apex I have differents functions to each radio button that displays hidden radio buttons.
I called this function like this:
  
<apex:selectRadio value="{!contact.LivesInAmerica__c}" label="Do you live in America?" id="rb1">
     <apex:selectoptions value="{!types}"></apex:selectoptions>
     <apex:actionSupport event="onchange" action="{!functionFirst}"/>
</apex:selectRadio>
<apex:selectRadio rendered="{!showRB1}" value="{!contact.Street__c}" label="Street">
     <apex:selectoptions value="{!types}"></apex:selectoptions>
</apex:selectRadio>
And this code on Apex Class Controller:
  
public PageReference functionFirst(){
        if(contact.LivesInAmerica__c == 'Yes'){
            showRB1= true;
        }
        else {
            showRB1= false;
        }
        return null;
    }

Thanks!

I made it work with:
  
<script type="text/javascript">
            window.onload = setFocus
            function setFocus() {
                if({!notFirstTime}) {
                    document.getElementById('{!$Component.button.save}').scrollIntoView();
                }
            }
</script>

Hi Nicolas
If you don't want to refresh the whole page then use reRender attribute. This attribute refreshes a particular section of VF page.

reRender="id" // here id is an identifier of a particular section in your VF Page which you want to refresh when a particular event occurs.
change your third line in VF Page with this below line--

<apex:actionSupport event="onchange" action="{!functionFirst}" reRender="rb1"/>

If this helps you marked this as solved.
