TYPO3 menu: how to set “entryLevel” dynamic?

问题

I'm trying to create a menu that displays in TYPO3 all subpages and the parent page. My problem is that I find no way to assign entryLevel dynamically.

I'm working with TYPO3 6.1
This is currently my typoscript for the menu.

lib.mainnavi = HMENU
lib.mainnavi {
    entryLevel = 1 
    1 = TMENU
    1.wrap = <ul> | </ul>
    1 {
        noBlur = 1
        NO {
          subst_elementUid = 1
          allWrap = <li id="link{elementUid}" class="first">| |*| <li id="link{elementUid}">| |*| <li id="link{elementUid}" class="last">|
          wrapItemAndSub = |</li>
        }
        ACT = 1
        ACT {
          subst_elementUid = 1
          allWrap = <li id="link{elementUid}" class="first current first_current">| |*| <li id="link{elementUid}" class="current">| |*| <li id="link{elementUid}" class="last current last_current">|          
          wrapItemAndSub = |</li>
        }
    }
}

Below is a picture to illustrate what I want.
When I go to "1", I want to see "FAQ", "GTC (EU)" and "GTC (USA)".
When I go to "FAQ", I want to see A-J and "1" as "back".
When I go to "A", I want to see "FAQ" as "back"

I can make the "back" menu with a seccond menu and special = browse. But I can't find a way to set entryLevel dynamically

回答1:

Entry level can get positive and negative values.

While the positive values are marking absolute level positions counting from the root page.

Root => 0
  - Page => 1
    - Page => 2
      - Current Page => 3

negative values will be relative and counted from the current page back to the root

Root => -4
  - Page => -3
    -Page => -2
      - Current Page => -1

This way you don't have to use conditions for every level, which would just bloat your caching tables.

Root => 0
  - Page => 1
    - Current Page => 2

Root => -3
  - Page => -2
    - Current Page => -1

回答2:

You can adjust the entryLevel setting with a condition below your TS code. Just have a look at the documentation for the treeLevel condition.

Use it like this:

[treeLevel = 2]
    lib.mainnavi.entryLevel = 2
[end]

There is a nother solution, that does not use entryLevel at all:

lib.mainnavi = HMENU
lib.mainnavi {
  special = directory
  special.value.field = uid 
    ...
}

This would create a menu of pages having the UID of the current page as PID, AKA subpages of the current page.

This did the trick for me:

lib.mainnavi = HMENU
lib.mainnavi {
    entryLevel = 1
    special = directory
    special.value.data = leveluid:-1

    # your code here ...
}
