Employment/Purpose

A portallayout lays out a container which can have multiple columns, and each column might have any number panels placed vertically with different heights. Portallayout allows users to drag-and-drop a panel to change its location.

When using Portallayout, you have to assign the width (either percentage or pixel) to each Portalchildren, or the result might depend on the browser, and not as expected.

Example

    <portallayout height="100%">
        <portalchildren width="50%">
            <panel height="50%" title="Calendar" border="normal">
                <panelchildren>
                    <calendar/>
                </panelchildren>
            </panel>
            <panel height="50%" title="Colorbox" border="normal">
                <panelchildren>
                    <colorbox/>
                </panelchildren>
            </panel>
        </portalchildren>
        <portalchildren width="50%">
            <panel height="100%" title="Editor" border="normal">
                <panelchildren>
                    <tbeditor/>
                </panelchildren>
            </panel>
        </portalchildren>
    </portallayout>

orient

since 7.0.0

Default: vertical

If you want the portallayout to be displayed as a row-based layout, you can specify orient="horizontal".

<portallayout orient="horizontal">
    <portalchildren width="50%">
        ...
    </portalchildren>
    <portalchildren width="50%">
                ...
    </portalchildren>
</portallayout>

Draggable Panel by Default

<panel> is draggable="true" without explicitly specifying when it’s inside a Portallayout. You can disable this by draggable="false".
