Hi,

When using the dropdown tree on safari using the bootstrap themes when the page has scrollbars and clicking on the dropdown the page scrolls up, even though there is available space:

Please see this Dojo which replicates the issue:

https://runner.telerik.io/fullscreen/uwoBEKiT/2

Open the above URL in Safari, chick on the dropddown and the page scrolls up and the dropdown is no longer visible.

Bug report

Regression introduced in R1 2020.

Reproduction of the problem

Reproducible in the demo.

1. Focus the DropDownTree.
2. Click the "Check all" checkbox.

Current behavior

The DropDownTree items are not checked. The issue is reproducible only if the checkbox is clicked. Clicking its label, or checking the checkbox with the keyboard (Space key) checks all items as expected.

Expected/desired behavior

All items are checked.

Environment

• Kendo UI version: 2020.1.219
• jQuery version: x.y
• Browser: [IE, Edge(Spartan) ]

1. open all options from top to bottom 

2. collapse the option from bottom to top

3. once the top option is collapsed - dropdown box stays at top

Hi
I have a problem with the DropDownTree component.
From a remote data source type json I am getting a tree with two levels of data but it only shows the first level.

Code:

$("#dropdowntree").kendoDropDownTree({
	dataSource: {
		transport: {
			read: {
				url: "/api/getData",
				type: "POST",
				dataType: "json",
				contentType: "application/json; charset=utf-8"
			}
		}
	},
	checkboxes: true
});

Response:

[
	{
		text: "Furniture", expanded: true, items: [
			{ text: "Tables & Chairs" },
			{ text: "Sofas" },
			{ text: "Occasional Furniture" }
		]
	},
	{
		text: "Decor", items: [
			{ text: "Bed Linen" },
			{ text: "Curtains & Blinds" },
			{ text: "Carpets" }
		]
	}
]

$("#dropdowntree").kendoDropDownTree({
	dataSource: {
		data: [
			{
				text: "Furniture", expanded: true, items: [
					{ text: "Tables & Chairs" },
					{ text: "Sofas" },
					{ text: "Occasional Furniture" }
				]
			},
			{
				text: "Decor", items: [
					{ text: "Bed Linen" },
					{ text: "Curtains & Blinds" },
					{ text: "Carpets" }
				]
			}
		]
	},
	checkboxes: true
});

Using setDataSource method on a working DropDownTree, with same initial settings leads to not working clea button and not expanding a collapsed node. 

Dojo: https://dojo.telerik.com/uLUNudEJ 

Steps (clear button):

1. Open dojo and check that everything works correctly

2. Click reload button (calls setDataSource)

3. Clear all button does not work and cannot deselect the item from the tag's clear button.

Steps (expand):

1. Open dojo and open popup to see everything expands as expected

2. Click reload

3. Open popup

4. The last (initially collapsed) node cannot be expanded.

Bug report

If the DropDownTree is configured without checkboxes (single selection), the X button shouldn't be present.

Reproduction of the problem

1. Open this demo - https://demos.telerik.com/kendo-ui/dropdowntree/index
2. Select an item from the DropDownTree

Current behavior

The clear button appears

Expected/desired behavior

The clear button shouldn't be present.
