I notice the expansion of nodes can be rather unreliable (sometimes clicking does nothing), and this warning pops up in the console when it actually does expand:
toggle() is deprecated, please use toggleExpanded()

Your demo does not have the reliability issue, but does still throw that warning up in the console.

I am using System.js if that makes a difference for this issue.

As the title says, I have some nodes with isExpanded: true, but the treeview is collapsed on startup.

var nodes =
    [
        {
            name: 'a',
            isExpanded: true,
            children: [
                {
                    name: 'b',
                    isExpanded: true,
                    children: [
                        { name: c', }
                    ]
                },
            ]
        },
        {
            name: 'b',
            isExpanded: true,
            children: [
                {
                    name: 'a',
                    children: [
                        { name: 'c' },
                    ]
                }
            ]
        }
    ];

Currently we must load lodash manually into the project when using systemJS.
This should be solved.

I suspect it's got something to do with lodash being defined as ambient dependency.

I've two questions

Can I give tree custom template ?
is it compatible with angular rc 3 ?

thanks

In my case I have a form inside a tree node and I want to use the SPACE key but preventDefault() is preventing me of adding white spaces in my input fields. Can you give me a suggestion how can I resolve that or maybe you plan to refactor that in the future?

Hello
The package.json is still referencing RC7. Can you update it to use 2.0.0 instead ?

Cheers

drag & drop not update view or model on drag end

I'm not using Typescript so I don't have nor use typings. It fails to install in the postinstall step as a result. I saw that the path is node_modules/.bin/typings install - you should just be able to say typings install and it should install based on the depended-on install of typings - no need to specify the full path.

drag & drop behaviour in the tree

Can you please update the tree component to the last angular rc ?

I'd like to filter the nodes, and focus all the nodes that satisfy the filter. Is that possible to do?

Suppose I have the following model which I pass to the tree component:

nodes = [{
    name: 'test',
    children: [{
        name: 'test-child'
    }]
}];

    nodes[0].name = 'test changed';

    nodes[0].children.push({name: 'test-child-2'});

    nodes[0].children = [{name: 'test-child-2'}];

Hi,

In the current implementation of the tree it is possible to select/deselect a node with keyboard, pressing on enter/space. I have a requirement to implement tree node template with text input that allows spaces. Default behavior of enter/space is prevented, so it is impossible to use space inside node template.

I suggest to allow configuration of keyboard navigation keys through options object.

Thanks

Any idea why the tree doesn't expand on page loading? Below is my configuration:

In the view inside the Tree element:
[nodes]="tree" [focused]="true" [options] = "treeOptions"

In the component:
treeOptions = {
isExpanded: 'expanded',
treeNodeTemplate: MyTreeNodeTemplate,
loadingComponent: MyTreeLoadingTemplate,
context: this
}

Json returned from the server contains "expanded":true

I have a tree that displays nodes. On each node i have a custom template, which offers the options Edit, Copy and Delete. When one of these options is pressed, i would like to open a modal window (using ng2-bootstrap) and ask the user to confirm their action.

Now i can do this, if I create a modal window in the custom template, but that seems like a lot of HTML to repeat for each node, so instead i would like to have my ModalComponent on the same component as my tree, and somehow raise an event when a button in a template is pressed....

How can i do this? Here is what i have so far

I am using angular2-tree-component with webpack and all the functionality works just fine. The only issue I see is that if I click on a parent node that has one or more children, the icon of the parent node does not change to the down arrow when the parent node is in expanded state.
From what I can see I dont need to add any CSS files, it should just work. What am I missing?
Thanks.

I just installed the component using angular rc3 and I have a bunch of loading element showing and when I click on a node every node expands. See gif below for an example.

Hi. I wanna display more than 1 field. Is it possible to display more than 1 field?

Test on IE

Any plans on when is this component going to be updated to support rc5 and ngModules?

The user can use check using the $event

how to active async load??

THANKS

Whats the best approach to styling the tree?

I encountered the problem, that the title field (displayField) is rendered twice. Same behaviour can be seen in your demo:

Bug or Feature? 😄

If you activate a node and then activate a different node without multiselect, there is no onDeactivate event fired for the first node. This basically forces you to maintain your own list of selected nodes instead of relying on the tree to handle it for you.

I'd submit a PR, but I want to wait until you decide what to do with #43.

The npm package does not contain the js file(s) of this component. This means the component can't be loaded with system.js. Do you have any plans to fix this (or am I missing something here)?

Thanks.

Since this is a library, forcing the user to use lodash is a problem.

In here there is a direct import of the whole lodash library.

It should be either removed and functionality should be manually written,.
Or, only required functions from lodash should be imported.

I have the tree in a component, but want to activate the first node in the tree by default.

How can this be done?

It would be nice to be able to say "this is expanded by default" - perhaps by doing expanded: true on the object. I don't want my tree to always be collapsed by default.

Can you publish it to npm please..... Ta

TreeNodes with children are 4px to the right of TreeNodes with no children. You can fix this by setting the left padding of .toggle-children-wrapper to 1px instead of 5px.

I'd submit a PR, but I want to wait until you decide what to do with #43.

I still get this:

Need to support these options:

• children padding - default
  • allow to supply a method that returns the children padding for each node
• per node padding
  • calculated by default as X * node.level
  • allow to override X
  • allow to supply a method that returns the padding for each node

Please update dependencies to support Angular 2 RC.2.

I have downloaded the code from the master branch, built the code and tried to then use it in my application....

Now for some reason i get the error above?

In my module, i am doing this

Hi,
how to filter on tree model?
thanks

The current setup will error when the local system does not have the typings global module.

There is a post install script that runs typings.

Since typings is fading away and @types is the de facto solution for type definition, maintained by MS I suggest moving to it.

With RC6 all components and pipes must now be declared via an NgModule. Unfortunately the following error message pops up since updating:

Can't bind to 'node' since it isn't a known property of 'TreeNode'. ("
      <TreeNode
        *ngFor="let node of treeModel.roots"
        [ERROR ->][node]="node">
      </TreeNode>
    </div>
"): TreeComponent@4:8

Please update dependencies to support RC.3.

Any plans to add drag and drop?

Would be good to have the possibility to select an node by the id. I did not find this possibility in the API. In this case should fire an event informing that the node has been selected.

One great tree component that i use is the jsTree (https://www.jstree.com) but it has the disadvantage of use jquery.

Follow my suggestion:
<Tree #tree [nodes]="nodes"></Tree>
<button (click)="tree.treeModel.selectNode(2)">next node</button>
nodes = [
{
id: 1,
name: 'root1',
isExpanded: true,
children: [
{
id: 2,
name: 'child1'
}, {
id: 3,
name: 'child2'
}
]
}
]

How to event tree ready?
@ViewChild('treeProcessi') private tree:TreeComponent;

onInizialized tree is undefined.

ngAfterViewChecked is called many times for tree variable.

Thanks

Under configuration, the new context option, this part includes an option called template, which should actually be treeNodeTemplate

MyComponent {
  treeOptions = {
    template: '{{ node.data.name }} <button ng-click="context.doSomething()">Go!</button>'
    context: this
  }

  doSomething() {
  }
}

MyComponent {
  treeOptions = {
    treeNodeTemplate: '{{ node.data.name }} <button ng-click="context.doSomething()">Go!</button>'
    context: this
  }

  doSomething() {
  }
}

I want to collapse, expand roots after initialization.

I have initialized a tree with 1 root, which has several children.
I have defined the tree as a ViewChild, and after console.logging the tree I can see in the console, that roots in treeModel is an array of length 1. But after console.logging tree.treeModel.roots I get empty array.
