Tree is not rendering
See original GitHub issueHi there, I don’t know why the tree is just render root, the children are not on version 6.0.1 and up. It works well on v3.2.3. Could you please help to check?
- This is my code: import { Component, OnInit, OnChanges } from ‘@angular/core’; import { ITreeOptions } from ‘angular-tree-component’;
declare var require: any;
@Component({
selector: ‘app-async’,
template: <tree-root #tree [options]="options" [nodes]="nodes"></tree-root>
,
styles: []
})
export class StartPageComponent implements OnInit {
ngOnInit() {
}
options: ITreeOptions = {
getChildren: this.getChildren.bind(this)
};
nodes: any[] = [];
asyncChildren = [
{
name: 'child1',
hasChildren: true
}, {
name: 'child2'
}
];
constructor() {
this.nodes = [
{
name: 'root1',
children: [
{ name: 'child1' }
]
},
{
name: 'root2',
hasChildren: true
},
{
name: 'root3'
}
];
}
getChildren(node: any) {
const newNodes = this.asyncChildren.map((c) => Object.assign({}, c));
return new Promise((resolve, reject) => {
setTimeout(() => resolve(newNodes), 1000);
});
}
}
- It renders as bellow:

Make sure you have imported the stylesheet in your main styles.scss or equivalent:
@import "~angular-tree-component/dist/angular-tree-component.css";
I have the same problem and i added the css import also but still continue to have the problem. But for me the import line is @import ‘~@circlon/angular-tree-component/css/angular-tree-component.css’; and not @import ‘~@circlon/angular-tree-component/dist/angular-tree-component.css’; since dist is not an available location in the library. I don’t know if that makes a difference though
