Angular tree component virtual scrolling is not working

Question

I have taken the files from folder of virtual scroll in my existing project to perform a POC on virtual scrolling.

https://github.com/CirclonGroup/angular-tree-component/blob/master/projects/example-app/src/app/virtualscroll/virtualscroll.component.ts

There is no virtual scroll enabled with the same code. Behavior at my end

If I run the project from github (angular-tree-component) I am getting the scroll. Reference of the working code: https://angular2-tree.readme.io/docs/large-trees

Answer 1

In my code somebody had overridden in overrides.scss the below line:

tree-viewport {
    overflow: visible;
}

Removing this line worked for me.
