Hello, I would like show a treeview like the following,
root |---dir1 | |----leave 1.1 | |----leave 1.2 |-----leave 0. 1 |-----leave 0.2 This view should also allow a user to select multiple leave nodes (think of selecting multiple catagories to charaterized a product). I checked the TreeView/TreeTable components in Wicket-Ext and found that they need to communicate with the sever-side every time a node is expanded or collapsed. This is a waste of bandwidth in my case, as my tree model never changes. Any suggestion on how I should implement a "fixed" treeview on the client side, and only pass data to the server after the user clicks a submit button?
