Hi I followed this code but my logout button is not at the right side of menubar.
here is my xhtml page
<h:body>
<p:menubar autoDisplay="false">
<p:menuitem value="Home" url="/index.jsf" />
<p:submenu label="Maintenance" >
<p:menuitem value="Course" url="/views/course/list.jsf" />
<p:menuitem value="Student" url="/index.jsf" />
</p:submenu>
<f:facet name="options">
<p:commandButton type="button" value="Logout" icon="ui-icon-extlink" />
</f:facet>
</p:menubar>
</h:body>
You should use a style="float: right;" inside the button or include the property into your css stylesheet.
