Can data that DynaTree uses be changed dynamically?
I have a complete set of data that relates to dynatree, but I want to display only a certain branch of the tree so I iterate over the data and take the node I want and create the tree, this works fine.
What I would like to do is have a button that makes the siblings of the current node visible. essentially a user is in charge of one node which they see by defaault, but they can see siblings of the current node if they need too.
I can re-iterate over the data and select the parent node and set the data to the parent but the tree doesnt update.
I've tried:
tree.reload();
tree.renderInvisibleNodes()
tree.redraw();
and setting the element to empty and recreating the tree with the new settings
$('#i2o-tree').empty();
$('#i2o-tree').dynatree(new_settings);
Just got this to work, Hope this helps someone in future.
Since dynatree is a jQuery plugin, if you really need to reload the data and re-render the tree you and call jQuery's 'destroy' method:
// destroy tree
$("#i2o-tree").dynatree("destroy");
// re-create tree with new settings/data
setupTree(tree_data, false);
