Hi,
this is not a question but a solution about rendertags.
The customer had pages with an opt_PageHidden to hide the page within the
navigation.
Even with CurrentIndex.HasChildren() we could get the case, that subitems
exist but all of them are hidden.
In this case, the UL nad nextlevel should not be created because the
submenu would be empty.
THis is how it works:
<reddot:cms>
<if>
<query
valuea="Context:CurrentPage.Elements.GetElement(opt_PageHidden).Value"
operator="!=" valueb="hidden">
<htmltext>
<li>
<a href="<%!! Context:CurrentIndex.GetUrl() !!%>"><%!!
Escape:HtmlEncode(Context:CurrentIndex.Headline) !!%></a>
</htmltext>
<if>
<query valuea="Context:CurrentIndex.HasChildren()"
operator="==" valueb="Bool:True">
<!-- Only when subpages exist -->
<!-- Create a variable -->
<output type="object"
object="Store:Set(boolVisibleSubPages,Bool:False)" />
<!-- Loop over the subpages -->
<foreach itemname="subnavList"
object="Context:CurrentPage.Elements.GetElement(lst_navigationMain).Value"
countername="listCounter">
<if>
<query
valuea="Store:subnavList[Int32:listCounter].Elements.GetElement(opt_PageHidden).Value"
operator="!=" valueb="hidden">
<!-- Only when a visible subindex is found -->
<!-- Set the variable to true -->
<output type="object"
object="Store:Set(boolVisibleSubPages,Bool:True)" />
</query>
</if>
</foreach>
<if>
<query valuea="Store:boolVisibleSubPages" operator="=="
valueb="Bool:True">
<!-- Only when a visible subindex was found -->
<htmltext>
<ul>
<navigation:nextlevel>
</ul>
</htmltext>
</query>
</if>
</query>
</if>
<htmltext>
</li>
</htmltext>
</query>
</if>
</reddot:cms>
