  <p>There are two kinds of behaviors: </p>
  <ul>
    <li><code class="language-markup">&lt;f:ajax/></code> send an ajax request</li>
    <li><code class="language-markup">&lt;tc:event/></code> do a full page reload</li>
  </ul>
  <p>Tag Library Documentation:
    <tc:link label="&lt;f:ajax/>" image="#{request.contextPath}/image/feather-leaf.png"

    <tc:link label="&lt;tc:event/>" image="#{request.contextPath}/image/feather-leaf.png"
             link="#{demoBundle.tagDocUrl}/#{apiController.currentRelease}/tld/tc/event.html"/></p>

  <tc:section label="Basic examples">
    <p>Type a text into the input field. After leaving the input field, the given text is shown in the output field.</p>
    <tc:section label="f:ajax">
      <pre><code class="language-markup">&lt;tc:in label="Ajax Input" value="\#{behaviorController.ajax}">
  &lt;f:ajax render="outAjax"/>
&lt;/tc:in></code></pre>
      <tc:in label="Ajax Input" value="#{behaviorController.ajax}">
        <f:ajax render="outAjax"/>
      </tc:in>
      <tc:out id="outAjax" label="Ajax Output" value="#{behaviorController.ajax}"/>
    </tc:section>

    <tc:section label="tc:event">
      <pre><code class="language-markup">&lt;tc:in label="Event Input" value="\#{behaviorController.event}">
  &lt;tc:event/>
&lt;/tc:in></code></pre>

      <tc:in label="Event Input" value="#{behaviorController.event}">
        <tc:event/>
      </tc:in>
      <tc:out label="Event Output" value="#{behaviorController.event}"/>
    </tc:section>
  </tc:section>

  <tc:section label="Change the event name">
    <p>It's possible to change the event name. For example if you want a double click event, change the event name to
      <code>dblclick</code>. This is done for the following two buttons.</p>

    <pre><code class="language-markup">&lt;tc:button label="Ajax Double Click">
  &lt;f:ajax event="dblclick" render="outCounter" listener="..."/>
&lt;/tc:button>
&lt;tc:button label="Event Double Click">
  &lt;tc:event event="dblclick" actionListener="..."/>
&lt;/tc:button></code></pre>
    <tc:button label="Ajax Double Click">
      <f:ajax event="dblclick" render="outCounter" listener="#{behaviorController.countUp}"/>
    </tc:button>
    <tc:button label="Event Double Click">
      <tc:event event="dblclick" actionListener="#{behaviorController.countUp}"/>
    </tc:button>
    <tc:out id="outCounter" label="Counter" value="#{behaviorController.counter}"/>
  </tc:section>

  <tc:section label="Advanced">
    <p><code class="language-markup">&lt;tc:event></code> may contain <code class="language-markup">&lt;f:ajax></code>
      and <code class="language-markup">&lt;tc:operation></code> tags.</p>
    <p>This is helpfull if the parent component cannot handle operations by itself.</p>
    <p><tc:badge value="Important" markup="danger"/>
      The <code>event</code> attribute of the ajax children will be ignored.</p>

    <tc:section label="Example">
      <p>An example can be found for
        <tc:link label="&lt;tc:row>" outcome="/content/20-component/080-sheet/30-event/sheet-event.xhtml"/>
        Option: 'open popup on click with AJAX'.</p>
      <pre><code class="language-markup">&lt;tc:row>
  &lt;tc:event>
    &lt;f:ajax execute=":::popup" render=":::popup" listener="..."/>
    &lt;tc:operation name="show" for=":::popup"/>
  &lt;/tc:event>
&lt;/tc:row></code></pre>
