Hi,
I think it’s a language barrier here.... I’m quite sure you don’t want "isfolder", you would use that to filter out (remove) certain documents based on whether they were folders or not. That won’t help with the order of the documents.
This way will give you the most control:
[[Ditto? &orderBy=`menuindex ASC` &documents=`235, 246, 252, 118, 74` &depth=`2` &display=`all` &total=`all` &showInMenuOnly=`1` &tpl=`nl_sidebar`]]
Then you set "Menu Index" on each document to make any order you want. If you have Doc Manager, (Modules, Doc Manager) that can go even faster. I believe the default Ditto order is by "publishedon ASC", although I may be mistaken.
Hope that helps,
Ciao, Dave
