Question

I am having a layout problem in one of my primefaces UI.
I basically have a table wrapped in a DIV with the code below. The last column should contain buttons that I wanted to arrange horizontally
so I enclosed them in a panelGroup

<div style="overflow: auto; height: 300px;">
    <p:dataTable >
        <p:column headerText="Column 1">
        </p:column>
        .
        .
        <p:column headerText="Actions">
            <h:panelGroup layout="span">
                <p:commandButton value="Edit" icon="ui-icon-scissors" />
                <p:commandButton value="Delete" icon="ui-icon-trash" />
            </h:panelGroup>
        </p:column>
    </p:dataTable>
</div>

However, when they are rendered the buttons are arrange vertically. Viewing the HTML code I notice that the buttons are both wrapped in a div
so thats why there is a newline between them.

How to fix this problem?

Thanks

Answer 1

Wrap them with a <h:panelGrid/> or a <p:panelGroup/>. This will render a table with two table cells in the same table row (so they must be appear in the same row):

With h:panelGrid:

<h:panelGrid columns="2">
    <p:commandButton value="Edit" icon="ui-icon-scissors" />
    <p:commandButton value="Delete" icon="ui-icon-trash" />
</h:panelGrid>

With h:panelGroup:

If you use h:panelGroup without style, styleClass or id attributes the layout attribute has no effect and no additional html will be rendered around your buttons. Anyway, adding the style:

<h:panelGroup style="white-space: nowrap">
    ....
</h:panelGroup>

makes them horizontally aligned, no matter which layout value you are using.
