I use Bootstrap_package v10 and Typo3 9, the menu processor doesn't show the level-3 and 4 for my pagetree.
I'm using the original templates from bootstrap package, the code is below:
10 = TYPO3\CMS\Frontend\DataProcessing\MenuProcessor
10 {
levels = 5
special = directory
special.value = 26969
expandAll = 1
includeSpacer = 1
as = mainnavigation
dataProcessing {
10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
10 {
references.fieldName = nav_icon
as = icon
if {
isTrue.stdWrap.cObject = COA
isTrue.stdWrap.cObject {
10 = TEXT
10.value = 1
10.if.isTrue = {$page.theme.navigation.icon.enable}
20 = TEXT
20.value = 1
20.if.isTrue = {$page.theme.navigation.dropdown.icon.enable}
}
}
}
}
}
and this is the fluid code :
<f:section name="MainNavigation">
<f:if condition="{menu}">
<ul class="navbar-nav">
<f:for each="{menu}" as="item">
<f:if condition="{item.spacer}">
<f:then>
</ul>
<ul class="navbar-nav">
</f:then>
<f:else>
<li class="nav-item{f:if(condition: item.active, then:' active')}{f:if(condition: item.children, then:' dropdown dropdown-hover')}">

<f:if condition="{theme.navigation.icon.enable} && {item.icon}">

</f:section>The fluid is calling a page child but i don't know if it is recursive or not so it can showa all levels, what am I missing there, it seems like i'm the first one that having this issue ?
Thanks in advance for any help.
First you should verify if the data is available for more than the first two levels:
insert a <f:debug title="mainnavigation">{mainnavigation}</f:debug> in your template.
Then inspect your templates whether they are ready to display more than two levels.
I can imagine your templates show the first level, for second level a partial is called, but that partial does not call itself if necessary.
Except if you need some level specific markup (e.g. 'class="level1") you can build up menus by stacking the levels inside each other (giving stacked uls). So you either have a recursive call with stacked menus of the same markup or you define a partial for each level with individual markup (or you define a variable which contains the current level and call the partial recursive).
it's even worse: both levels are written out in the same template file, no partial (or section) is used.
I would change it to:
(I stayed with one file and instead of an additional partials I call a section, which can be in the same file)
<f:section name="MainNavigation">
<f:if condition="{menu}">
<ul class="navbar-nav">
<f:for each="{menu}" as="item">
<f:render section="subLevel" arguments="{item:item}" />
</f:for>
</ul>
</f:if>
</f:section>
<f:section name="subLevel">
<f:if condition="{item.spacer}">
<f:then>
<li class="dropdown-divider"></li>
</f:then>
<f:else>
<li class="nav-item{f:if(condition: item.active, then:' active')}{f:if(condition: item.children, then:' dropdown dropdown-hover')}">
<a href="{item.link}" id="nav-item-{item.data.uid}" class="nav-link{f:if(condition: item.children, then:' dropdown-toggle')}"{f:if(condition: item.target, then: ' target="{item.target}"')} title="{item.title}"{f:if(condition: item.children, then:' aria-haspopup="true" aria-expanded="false"')}>
<f:if condition="{theme.navigation.icon.enable} && {item.icon}">
<span class="nav-link-icon">
<f:if condition="{item.icon.0.extension} === svg">
<f:then>
<bk2k:inlineSvg image="{item.icon.0}" width="{theme.navigation.icon.width}" height="{theme.navigation.icon.height}" />
</f:then>
<f:else>
<f:image image="{item.icon.0}" alt="{item.icon.0.alternative}" title="{item.icon.0.title}" width="{theme.navigation.icon.width}" height="{theme.navigation.icon.height}" />
</f:else>
</f:if>
</span>
</f:if>
<span class="nav-link-text">{item.title}<f:if condition="{item.current}"> <span class="sr-only">(current)</span></f:if></span>
</a>
<f:if condition="{item.children}">
<ul class="dropdown-menu" aria-labelledby="nav-item-{item.data.uid}">
<f:for each="{item.children}" as="child">
<f:render section="subLevel" arguments="{item:child}" />
</for>
</ul>
</f:if>
</li>
</f:else>
</f:if>
</f:section>
Notice the changed markup for spacer in the first level!
Further changes might occur as I have not compared the code but concentrated on building up clean markup.
Increasing a 'parameter' for the recursion.
for an increasing value (level1, level2, level3...) you need a viewhelper in TYPO3 prior version 9:
this viewhelper can be realised in typoscript:
lib.math = TEXT
lib.math {
current = 1
prioriCalc = 1
}
then you can change the initial call to the SubLevel section to:
<f:render section="subLevel" arguments="{item:item,level:1}" />
Now you have a fluid variable level with the value 1.
the recursive call must be changed to:
<f:render section="subLevel" arguments="{item:child,level:{f:cObject(typoscriptObjectPath:'lib.math', data:'{level}+1')}}" />
for increasing values 2, 3, 4 ...
