Sticky

Sticky component positions the target component as fixed so that the component stays in window viewport during scrolling.

Prime-face sticky component doesn't work as its documented on prime-faces documents. 

In-order to use sticky component correctly, you need to have both target component and sticky component in same parent component. 

As shown in example here:

<j:slot id="sSticky" width="4">

<h:panelGroup id="stickyGroup" styleClass="jeeslSticky">

   <p:panel id="panel" header="Sticky Panel" styleClass="jeeslPanel" >

<p:panelGrid columns="1" columnClasses="jeeslGrid100">

<h:outputText value="#{stylePanelTableBean.element}"/>

</p:panelGrid>

</p:panel>

<ofx:outputSection id="ofx" value="#{appCmsCacheBean.buildById(localeCode,25)}"/>

</h:panelGroup>

<p:sticky target="stickyGroup" />

</j:slot>

To group the components you can use panel group component with supporting style class jeeslSticky.

The style for jeeslSticky (.jeeslSticky > * {margin: 0 5px 10px 5px;}) has already been included in JeeslShowcase.
