Nested Tree Angular

[Rancov_Miroslav]

Hi, I just started with radzen and I wanna make a nested tree. How do I do this?
This is my Array of obj
Arr= [
{Id:1,
ParentId:0,
DocumentName:First Document
},
{Id:4,
ParentId:1,
DocumentName:Child 1
}
];
Thank you!

There is an example in this article: https://www.radzen.com/documentation/tree/

Tank you for your response, I tried, but it's not working (wanna match Id === ParentId), olso tied load loadash but when I recompile the application it removes the loadash. Thanks!

The example shows how to:

• Access current node data using ${event.data}
• Access current node level using ${event.level}
• Set node children using ${event.children}

For this particular example we've used non homogeneous data (each level have different properties) and you can find example with homogeneous data (self-referencing) in this thread:

Question regarding tree to show recursive data structure

You want top -> down structure, right? Northwind Employees is a self-referencing table as well, here is how to display it: First get the employees not reporting to anyone and use it for first level: [image] [image] Then get the employees reporting to expanded employee: [image] [image] Here is how it looks runtime: [image]

Again, these are just examples that can be adapted to your scenario and data.
