{namespace neos=TYPO3\Neos\ViewHelpers}
{namespace ts=TYPO3\TypoScript\ViewHelpers}

<ul{attributes -> f:format.raw()}>
<f:render section="itemsList" arguments="{items: items}" />
</ul>

<f:section name="itemsList">
	<f:for each="{items}" as="item">
		<li{ts:render(path:'{item.state}.attributes') -> f:format.raw()}>
		<neos:link.node node="{item.node}">{item.label}</neos:link.node>
		<f:if condition="{item.subItems}">
		  <f:comment>Hide subItems if current node is not active</f:comment>
			<f:if condition="{item.state} != 'normal'">
				<ul>
					<f:render section="itemsList" arguments="{items: item.subItems}" />
				</ul>
			</f:if>
		</f:if>
		</li>
	</f:for>
</f:section>
