The vbox component is used to create a vertically oriented box. Added components will be placed underneath each other in a column.

Notice that hbox and vbox are designed to provode more sophisticated layout, such as splitter, alignment and packing. If you need only the layout feature, it is suggest to use Hlayout and Vlayout instead, since the performance is much better (due to the use of HTML DIV instead of TABLE).

        <hlayout forEach="${packs}" height="150px" width="600px">
            <custom-attributes pack="${each}"/> 
            <div hflex="1" vflex="1" sclass="box">
            <vbox forEach="${aligns}" align="${each}" pack="${pack}" hflex="1" vflex="1" sclass="box">
                <button label="1" />
                <button label="2" />
                <button label="3" />

Since 5.0.0

Cell Component

In ZK5, we have introduced a new component named Cell which can be embedded into a Grid or Box (Hbox and Vbox) to fully control the layout and the style. You can now use the rowspan or the colspan property to layout your Grid, for example a content cell can now cross over multiple rows. The code below demonstrates how to do this:

    <cell sclass="years">

Since 5.0.0


Box component is consisted by Table element. Therefore, when put Input element like Textbox, Combobox inside Box component, specify width and height to Box component will be ignored when browser try to render table element.

For example,

<hbox height="200px" width="200px" style="border: 1px solid red">
    <textbox hflex="1" value="1" />
    <textbox hflex="1" value="1" />

You will see the Box width exceed 200px. Also check the sample with pure HTML in jsfiddle.
