[TYPO3] Test for Treelevel inside a TMENU item

[Livius Agrippa]

Hi,

I want to create a menu with a "complex" picture after the active item.
But I want to remove this when the subitem is selected

Here is the code:
#the left menu
# Menu cObject
temp.menu = HMENU
temp.menu.entryLevel = 1
temp.menu.wrap = | &nbsp;<br />

  # First level menu-object, textual
temp.menu.1 = TMENU
temp.menu.1 {
    # Normal state properties
  NO.allWrap = <div id="idlevel1no" class="menu-left-level1-no"><table
width="100%" border="0" cellspacing="0" cellpadding="0"><tr><td
class="menu-left-level1-no-link" > | </td><td
class="menu-left-level1-no-picture"><img
src="fileadmin/template/images/no-link.gif" /></td></tr></table></div>
  NO.RO = 1

    # Enable active state and set properties:
  ACT = 1

  [treeLevel = 1]
  ACT.allWrap = <div class="menu-left-level1-no"><table width="100%"
border="0" cellspacing="0" cellpadding="0"><tr><td
class="menu-left-level1-no-link" > | </td><td
class="menu-left-level1-no-picture"><img
src="fileadmin/template/images/no-link.gif" /></td></tr></table></div>
  [else]
  ACT.allWrap = <div class="menu-left-level1-act"><table width="100%"
border="0" cellspacing="0" cellpadding="0"><tr><td rowspan="3"
class="menu-left-level1-act-link"> | </td><td
class="menu-left-level1-act-big01"><img
src="fileadmin/template/images/big_01.gif" width="15" height="7"/></td>
</tr><tr><td class="menu-left-level1-act-big02"><img
src="fileadmin/template/images/big_02.gif" /></td></tr><tr><td
class="menu-left-level1-act-big03"><img
src="fileadmin/template/images/big_03.gif" width="15"
height="7"/></td></tr></table></div>
  [global]
}

 # Second level menu-object, textual
temp.menu.2 = TMENU
temp.menu.2 {
    # Normal state properties
  NO.allWrap = <div class="menu-left-level2-no"><table width="100%"
border="0" cellspacing="0" cellpadding="0"><tr><td
class="menu-left-level2-no-link"> | </td><td
class="menu-left-level2-no-picture"><img
src="fileadmin/template/images/no-link.gif" /></td></tr></table></div>

    # Enable active state and set properties:
  ACT = 1
  ACT.allWrap = <div class="menu-left-level2-act"><table width="100%"
border="0" cellspacing="0" cellpadding="0"><tr><td rowspan="3"
class="menu-left-level2-act-link"> | </td><td
class="menu-left-level2-act-small01"><img
src="fileadmin/template/images/small_01.gif" width="15"
height="6"/></td></tr><tr><td class="menu-left-level2-act-small02"><img
src="fileadmin/template/images/small_02.gif" /></td></tr><tr><td
class="menu-left-level2-act-small03"><img
src="fileadmin/template/images/small_03.gif" width="15"
height="6"/></td></tr></table></div>

  wrap = <div class="menu-left-level2"> | </div>
}

But the test for TREELEVEL doesn't work insite a TMENU item.
[treeLevel = 1]
[else]
[global]

Can someone help me with a solution?

Best regards,
Livius
