borderlayout is not loading full on the screen

Question

I'm new in ZK and I'm trying to load map but it is not loading full because of vflex = "min". I'm able to see half screen but not seeing any scroll. I have tried to set vflex = "full", "1" and "max" but still borderlayout is not loading in full. Below is the code of zul file:

<vlayout>
                                        <div/>
                                        <borderlayout vflex="min">
                                            <west>
                                                <vlayout>
                                                    <vlayout/>
                                                    <groupbox width="280px">
                                                        <listbox height="240px"/>
                                                        <hlayout>
                                                            <button/>
                                                            <button/>
                                                        </hlayout>
                                                    </groupbox>

I put your zul on https://zkfiddle.org/sample/3ght56j/1-borderlayout-is-not-loading-full-on-the-screen

It looks like:

Is this what you expected? Could you decribe more clear about " not loading full "? or post a screenshot?
