Typo3 - TMENU get Content from Colpos - typo3

Question

i have an TMENU, in that Menu I would have the Content from the Subpages in the Menu. On every Page is an Col (colpos=0) with Content. Is it possible to get the Content from there to the Menu?
lib.mainmenu = HMENU
lib.mainmenu {
1 = TMENU
1 {
wrap = <ul id="mainmenu">|</ul>
expAll = 1
NO {
wrapItemAndSub = <li>|</li>
ATagParams = class="drop"
}
}
2 = TMENU
2 {
wrap = <div class="dropdown_produkte"><div class="nav-tabs"><ul>|</ul></div></div>
NO {
wrapItemAndSub = <li>|</li>
}
2.40 = CONTENT
2.40 {
table = tt_content
select.pidInList.field = pid
select.where = colPos=0
select.languageField=sys_language_uid
wrap = <div class="teaser">|</div>
}
}
}

Answer 1

There is already such a menu defined in css_styled_content
typo3/sysext/css_styled_content/static/setup.txt
# "Menu of subpages to these pages + sections - liststyle"
7 < .1
7 {
stdWrap {
outerWrap = <ul class="csc-menu csc-menu-7">|</ul>
}
1.expAll = 1
2 < .1
2 {
sectionIndex = 1
sectionIndex.type = header
wrap = <ul>|</ul>
NO.wrapItemAndSub = <li class="csc-section">|</li>
}
}
If you are going to use typoscript in your project (wich you hardly need anymore when you develope with fluid + vhs) than css_styled_content is always a good reference point

Here is my Solution
lib.mainmenu = HMENU
lib.mainmenu {
1 = TMENU
1 {
wrap = <ul id="mainmenu">|</ul>
expAll = 1
NO {
wrapItemAndSub = <li>|</div></li>
ATagParams = class="drop"
}
submenuObjSuffixes = a || b || c || d || e
}
2a < .1
2a {
wrap = <div class="dropdown_produkte">|</div>
stdWrap.cObject = COA
stdWrap.cObject {
20 = HMENU
20 {
special = directory
special.value.data = field:pid
1 = TMENU
1 {
expAll = 1
wrap = <div class="nav-tabs"><ul>|</ul>
NO {
wrapItemAndSub = <li>|</li>
#stdWrap.dataWrap = <h2>|</h2>
#linkWrap = | |*| /
ATagParams = class=submenu
}
ACT < .NO
ACT = 1
ACT {
ATagParams = class=submenuActive
}
RO < .ACT
}
}
40 = CONTENT
40 {
table = pages
select {
pidInList.field = pid
orderBy = sorting
}
renderObj = COA_INT
renderObj {
10 = TEXT
#10.field = title
10.wrap = |
20 = LOAD_REGISTER
20 {
meinRegister.cObject = TEXT
meinRegister.cObject.field = uid
}
50 = COA
50 {
###########
20 = CONTENT
20 {
table = tt_content
select {
pidInList.data = register:meinRegister
where = colPos=0
}
}
###########
}
}
}
}
}
}

As I faced a similar issue today, I wanted this question to be up to date. (Using TYPO3 8.7.4 with fluid_styled_content.)
lib.mainmenu = HMENU
lib.mainmenu {
1 = TMENU
1 {
wrap = <ul id="mainmenu" class="level1">|</ul>
expAll = 1
NO {
wrapItemAndSub = <li>|</li>
ATagParams = class="drop"
}
}
2 < .1
2 {
wrap = <div class="wrapper">|</div>
stdWrap.innerWrap = <ul class="level2">|</ul>
stdWrap.append = CONTENT
stdWrap.append {
table = tt_content
select {
pidInList.field = pid
where = colPos = 5 and deleted = 0 and hidden = 0
}
stdWrap.wrap = <div class="content">|</div>
}
}
3 < .2
3 {
NO.wrapItemAndSub = <li>|</li>
wrap = <ul class="level3">|</ul>
stdWrap.append >
}
}
That way (of course I simplified it here) I was able to add custom populated content from a specific column (defined in a backend_layout) to be rendered inside a navigation panel.
