Display Table

[marcelokabula]

I have a page what has a tree structure where exists files in folders. The tables with the file's names are hidden with "style='display:none;'". After to click a folder, the file's names are viewed with "...tableobject.style.display='';". To close a folder do "...tableobject.style.display='none';".
The problem is what when to click a file name, to view the file's body, and after, to click on BACK, the tree structure is closed again. How to resolve this?

You could perhaps save which folders are 'open' via a cookie and then check that cookie on page reload?
