Infinite Hierarchical Grids with Heterogeneous Structures in Kendo UI for Angular

Hi.

I'm exploring the possibilities of implementing hierarchical grids in Kendo UI for Angular and would like to know if it is possible to create grids with an infinite (or unpredictable) number of levels, each having heterogeneous structures.

Specifically, the requirement would involve different structures at each level (i.e., different columns and data types), and the number of nested levels is not known in advance.
Is there a way to dynamically handle these scenarios within the Kendo UI for Angular grid component?

I would appreciate any insights, examples, or suggestions on how to approach this.

Regards.

Long Progress Bar Animation Time When Reducing Steps in Stepper

I've got a use case where the number of steps in a vertically oriented stepper are dynamic.

If the number of steps is decently high (like, above 10) and the current step is also high, reducing the number of steps to a small value causes a very long and weird looking animation of the progress bar.

Here is a stackblitz demonstrating the issue

Turning off animations or reducing the time would mitigate this problem, but I think the animations are nice to have, especially when progressing through the stepper in a more traditional fashion.

Kendo grid does not maintain `resizable` when using `virtual-scroll` with *ngIf

There is a problem in kendo-grid using `virtual-scroll` that does not accept changing the grid-row dynamically. Problem highlighted in this question:

https://www.telerik.com/forums/is-there-a-way-to-dynamically-set-rowheight-in-a-kendo-grid

The solution was to use *ngIf with true and false, but using resizable, and toogle the `show` property. It doesn't save the previous measurement, and I have to make it manual resizable.

stackblitz:
https://stackblitz.com/edit/angular-fxdtag-rutrah?file=src%2Fapp%2Fapp.component.ts

step 1: change the columns resizable
step 2:change the row heigh (pressing the button)

My Kendo Grid properties:
  <kendo-grid  
  [selectable]="selectableSettings"
  (selectedKeysChange)="keyChange($event)"
  kendoGridSelectBy="id"
  [selectedKeys]="mySelection"
  >
Before update everything was fine I mean, I had correct objects (ids) into mySelection array number property.
Defined property into component:
    mySelection: number[] = [];
Selectable settings:
        this.selectableSettings = {
          checkboxOnly: true,
          mode: "multiple"
        };
KeyChange method:
    keyChange(e){
        this.closeEditor();
        if(e.length > 0) {
            this.isSelectionDisabled = false;
        } else {
            this.isSelectionDisabled = true;
        }
        this.extractDataItems = [];
        this.extract();
    }
Extract method:
    extract() {
        this.mySelection.forEach(idx => {
            this._subs.add(
                this.timeBookings$.pipe(
                    map(items => items.find(item => item.id === idx)
                )).subscribe(r => {
                    if(this.mySelection.length > 0 && r) {
                        this.extractDataItems.push(r);
                    }
                })
            );
        });
    }
Important!
When I'm selecting some rows - mySelection is always empty.
I know that in keyChange(e) method I can do something like:
this.mySelection = e;
and everything will work as should but why it was working correctly before update and after not?
Parameter of:
keyChange(e) - parameter e has correct value all the time

[Solved] Bug: Unnecessary console warning when sticky grid set with responsive column enabled

I've got a kendo grid with a responsive column set up as described in the docs

I also made a column sticky on the part of the grid that renders when the screen is larger.

I get this console warning because my responsive column does not (and cannot have) an explicit width set:

"Sticky columns feature requires all columns to have set width."
