What is the event that triggers BEFORE parsing the document ?

For the snippet DropMenu I try to change the document root depending on the current document.
So I wrote a plugin that checks the current document id.

Anyway - ’OnParseDocument’ does not seem to influence the behavior of the DropMenu snippet because it seems to be parsed before ?

My idea:

• create a template variable called ’docRoot’, set it to 0 by default
• in the template I defined the Dropmenu-generation
  
  [[DropMenu?&hereClass=`currentPage`&topnavClass=`menuList`&levelLimit=`3`&removeNewLines=`true`&startDoc=`[*docRoot*]`]]
  
• 
  create a plugin that shall be triggered by ’OnParseDocument’ and shall change the value of [*docRoot*]
  
  $id = $modx->documentIdentifier;
  $parentId = $modx->getParent($id,1,’id’);
  $parentId = $parentId[’id’];
  $rootArray = new Array();
  $rootArray[’aendern’] = 57; # folder _Aendern
  $rootArray[’gucken’] = 56; # folder _Gucken
  
  if ($id==50 || $parentId==50)
  $modx->documentObject[’docRoot’] = $rootArray[’aendern’];
  else
  $modx->documentObject[’docRoot’] = $rootArray[’gucken’];
  

But it seems the menu is created before the plugin is called because I can write here whatever I want - it does not do anything ?

PS:
I got an idea why that does not work - there is no way to set the template variable dynamically for documents ?
Therefore $modx->documentObject[’docRoot’] does not work, what a pity

You could try using the ultimateparent snippet along with dropmenu to achieve the same result:

I tried to call DropMenu with different startDocs, provided by a - manually edited - TV. And it didn’t work.
But it did work, when I put the whole DropMenu-Snippet call into the TV. So, if you use a snippet, which generates a TV, containing the complete call with the (dynamic) docroot-param, and not only the latter, I guess it could work...
