Global tooltip binds to clickable elements with title attributes. Ajax updates are supported as well, meaning if target component is updated with ajax, tooltip can still bind.
<div class="card">
<p:tooltip/>
<h:form>
<h:panelGrid columns="2" cellpadding="10">
<h:outputText value="Input: "/>
<p:inputText pt:data-tooltip="Tooltip for an input"/>
<h:outputText value="Link: "/>
<h:outputLink value="#" pt:data-tooltip="Tooltip for a link">
<h:outputText value="About"/>
</h:outputLink>
<h:outputText value="Button: "/>
<p:commandButton value="Update" pt:data-tooltip="Update components" update="@parent"/>
</h:panelGrid>
</h:form>
</div>
