This is a Blaze template to be used to display a tree (using jsTree) right from a collection.

Demo

See the demo and its source.

Usage

Installation

meteor add qnipp:treeview

Mount the tree in your Blaze template

{{> TreeView treeArgs }}

Configure the tree in a template helper

This is a short configuration to show a tree, e. g. for navigation purposes. It contains no events to alter the tree.

Template.templatename.helpers({
  treeArgs: {
    collection: collection,
    subscription: subscription,
    events: {
      changed: function(e, item) {
        console.log("Item " + item + "selected.");
      }
    }
  }
});

Configuration options

See the demo to see different configurations in action.

Data source

collection sets the collection to be used.
subscription sets the subscription for the template.
processNode a function(node,item) that allows to modify the tree nodes (node parameter) for jsTree, e.g. for adding properties to it for a certain plugin. The database item is passed as item.
getNodes is a function(parent), which returns the nodes for a given parent as cursor or array.
mapping contains a mapping from the fields from the data source to the tree fields. If a string is set, this field is taken from the orginal data. If a function is given, the function is called with the signature function(item). item is the row in the database.
parent: The field containing the id of the parent node.
text: The text to be used at the nodes.
icon: The icon to be used for this node.
state: The state for the given node as object. It contains three attributes:
- selected: The node is selected.
- opened: The node is opened, the children are shown.
- disabled: The node is rendered disabled.
liClass: The class to be used on the LI element.
aAttr: Attributes for the A element.

Tree configuration

parent shows only nodes below this parent. If not set, the parent node is identified by parent null.
select selects a node, when the tree is rendered. It takes core to open the parent nodes.
openAll opens all nodes on loading, if set to true.
jstree can be used to set the jsTree configuration options.
plugins activates one or more of the available plugins.

Events

Events are configured in the events property. It allows the following keys:

changed is called, when the selection changes.
create is called, when a new node is to be created. It is created with a default name, which is renamed afterwards.
rename is called, when an existing node is renamed.
delete is called, when a node is deleted.
copy is called to copy the selected nodes.
move is called to move the selected nodes.

The function signature is function(e, item, data).

e is the original event.
item contains the id of the respective item, or a list of ids in the case of the changed event. The root node has the id #.
data is an array with additional data, dependent of the event:
text contains the new name of a renamed node.
parent contains the parent for a new or copied or moved node.
position contains the position of a copied or moved node.
