Arranging components automatically

Hello

I have a JSF page which includes a Group Panel and four HyperLinks in it. When one of the links' rendered property is set to false, the others doesn't arrange automatically.

The unrendered link's place seems empty. I want the other links to locate themselves up.

Here's my code:

<webuijsf:panelGroup binding="#{menu.groupPanel1}" id="groupPanel1"

separator="<br/>" style="height: 153px; left: 5px; top: 20px; position: absolute; width: 83px">

<webuijsf:hyperlink binding="#{menu.hyperlink1}" id="hyperlink1" text="Hyperlink1"/>

<webuijsf:hyperlink binding="#{menu.hyperlink2}" id="hyperlink2" text="Hyperlink2"/>

<webuijsf:hyperlink binding="#{menu.hyperlink3}" id="hyperlink3" text="Hyperlink3"/>

<webuijsf:hyperlink binding="#{menu.hyperlink4}" id="hyperlink4" text="Hyperlink4"/>

</webuijsf:panelGroup>

For example, when the hyperlink2 's rendered property is set to false, hyperlink3 and hyperlink4 doesn't move and fill its place.

How can I do that?

Thanks.
