TMENU in Typo3 - insert url from level above

Question

I have a TMENU, and in that menu I would like to insert an URL from "Level 1" into a wrap item in "Level 2".

Current TypoScript looks like this:

10 = HMENU
10 {
    1 = TMENU
    1 {
        expAll = 1

        NO = 1
        NO.allWrap = <li>|</li>
        NO.allWrap.insertData = 1
        NO.ATagTitle.field = abstract // description // title
    }

    2 = TMENU
    2 {
        expAll = 1
        stdWrap.wrap = <ul><li><a href="*****URL FROM LEVEL 1 SHOULD BE HERE*****"></a></li>|</ul>

        NO = 1
        NO.allWrap = <li>|</li>
        NO.allWrap.insertData = 1
        NO.ATagTitle.field = abstract // description // title
    }
}

Any hints? Thanks for helping!

stdWrap properties are executed in a defined order (as they appear in documentation), see https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/Functions/Stdwrap.html#prepend

Knowing that prepend is executed before wrap3 allows to solve this challenge.

page = PAGE
page.10 = HMENU
page.10 {
    1 = TMENU
    1 {
        expAll = 1
        NO = 1
        NO.allWrap = <li>|</li>
        NO.allWrap.insertData = 1
        NO.ATagTitle.field = abstract // description // title
    }

    2 = TMENU
    2 {
        expAll = 1
        stdWrap.prepend = TEXT
        stdWrap.prepend {
          # remove `value` if page title shall be used
          value = URL from Level 1
          # using <current-page>.pid value pointing to previous level
          typolink.parameter.field = pid
          wrap = <li>|</li>
        }
        # `wrap3` is executed after `prepend`
        stdWrap.wrap3 = <ul>|</ul>

        NO = 1
        NO.allWrap = <li>|</li>
        NO.allWrap.insertData = 1
        NO.ATagTitle.field = abstract // description // title
    }
}

On a page-tree like this

+- A
|  +- AA
|  +- AB
|
+- B
   +- BA
   +- BB

The rendered HTML result looks like this

<li><a href="/ts/a" title="A">A</a></li>
<ul>
  <li><a href="/ts/a">URL from Level 1</a></li>
  <li><a href="/ts/a/aa" title="AA">AA</a></li>
  <li><a href="/ts/a/ab" title="AB">AB</a></li>
</ul>

<li><a href="/ts/b" title="B">B</a></li>
<ul>
  <li><a href="/ts/b">URL from Level 1</a></li>
  <li><a href="/ts/b/ba" title="BA">BA</a></li>
  <li><a href="/ts/b/bb" title="BB">BB</a></li>
</ul>

Update on custom rendering replacing static value property

Instead of using property stdWrap.prepend.value (like shown in example above), other cObject instructions could be used as well - in this case for instance RECORDS (see https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/ContentObjects/Records/Index.html)

The following example renders fields nav_title (and if that's not defined title as fallback) of the parent page.

page.10 {
    # ...
    2 {
        # ...
        stdWrap.prepend {
            # using `cObject` instead of `value`
            cObject = RECORDS
            cObject {
                tables = pages
                source.field = pid
                # rendering definition for retrieved record of table pages
                conf.pages = TEXT
                # `//` is used as fallback delimiter here, NOT as comment
                conf.pages.field = nav_title // title
            }
            # ...
