Hello, I'm trying to do the following: - documents containing a tree navigation are created dynamically using standard_header and footer. - the navigation tree is NOT located in a frame but in a table cell which is reloaded together with the rest of the page each time a link in that navigation is selected - the navigation tree is automatically created by using a dtml-method. The problem that occurs is, that the tree`s open/close state is not correctly maintained over the different documents. A solution to that might be to append the state of the tree after selection of a link to the it's URL as ?tree-s=.... ; that means pass the future state of the tree to the selected page by using URL-Parameters. Any ideas how to do that or any other ideas? Thank you Marcus
