The documentation at  https://docs.telerik.com/kendo-ui/api/javascript/ui/toolbar/configuration/items.menubuttons does not mention the children of a splitButton can have their own click handlers. It's not present in the typings either.

However, this does work: https://dojo.telerik.com/@GaloisGirl/UYeBewEX

Somewhat related is this bug: https://github.com/telerik/kendo-ui-core/issues/4542  . Documenting the behavior would be useful in accurately describing this bug.

In the KendoToolBar item configuration, there is currently a property called "overflow". The values of this property are: "never", "always", and "auto" (default). If the item.overflow value is set to "never" then the item remains in the toolbar and is not added to the overflow menu when the window shrinks. If the value is set to "always" or "auto", then the item is displayed in the overflow menu. The problem, however, is that sometimes you may want a toolbar item to disappear when the page shrinks, but you don't want or need it in the overlow menu.

A specific example is a toolbar item of type "separator". When the separator item.overflow is set to "auto", it adds a gap in the overflow menu between other items. I don't want this gap. Therefore, I set the separator item.overflow to "never". Unfortunately, this means that the separator remains on the toolbar. In the case where I have several separators in the toolbar with overflow set to "never", these all just stack up next to each other in the toolbar as the window is shrunk. I want them to disappear, but also not show up in the overflow menu. An overflow value of "hidden" could solve this problem.

BUG: setting a kendo ToolBar item.hidden with type of separator does not work. The separator is still displayed. For example:
```
$("#mytoolbar").kendoToolBar({
    items: [
        {
            type: "button",
            text: "button 1",
            hidden: true
        },
        {
            type: "spearator",
            hidden: true
        }
    ]
});
```

In this case, the button is hidden but the separator is not.

Describe the bug
In IE11 on resizing horizontally the browser window, the text of the ToolBar's tools overlaps.

To reproduce
Steps to reproduce the behavior:

1. Open: dojo example in IE11.
2. Resize the browser window making it narrower.

The tools size is not properly calculated and text overlapping can be observed (see the screenshot linked below). Overflow hidden is not set to the button tool and the k-input elements are resized on resizing the browser window.

The following CSS rule can be used as a workaround:

.k-toolbar .k-button,
.k-toolbar .k-input {
  overflow: hidden;
  flex: 0 0 auto;
}

Expected behavior
The ToolBar tools should properly resize on browser window resize. No text overlapping should occur.

Affected package (please provide)

• theme-default
• theme-bootstrap
• theme-material

Affected suites (please provide)

• Kendo UI for jQuery

Affected browsers (please provide)

• IE version: 11

Build system information (please provide)

• OS: Windows
• Node version: N/A
• NPM version: N/A

Additional context
N/A

• Create a Toolbar with 2 SplitButtons in the Overflow
• Use Keyboard to open the Overflow Menu
• Keyboard Navigation is trapped in the first SplitButton and the second SplitButton can not accessed via Keyboard Navigation

See the following dojo: https://dojo.telerik.com/UtoTOcUD

I tested the toolbar example https://demos.telerik.com/kendo-ui/toolbar/keyboard-navigation with a keyboard and screen reader (NVDA) and found the following issues:

1. Buttons are rendered as links. The SR announces the first button as "Button visited link". Apparently, there is an undocumented option useButtonTag (https://github.com/telerik/kendo-ui-core/issues/4730) that's also missing from the typings. I have to manually add 'role: "button"' to every single button to make my toolbar compliant.

2. Toggle buttons state is not announced.
 
3. The overflow menu button has no caption and is announced by the SR as "blank".

4. The overflow menu button has no visible focus styling (screenshot attached).

5. Selecting an item from the overflow menu throws the focus out of the page.

Bug report

The Toolbar's overflowAnchor property is missing from the Kendo typing definitions. It is also not available in the Toolbar's API.

Reproduction of the problem

Current behavior

Typing definitions for overflowAnchor are missing.

Expected/desired behavior

The overflowAnchor property should be available for the Toolbar and added to the API as well.

Environment

• Kendo UI version: 2019.2.619
• jQuery version: x.y
• Browser: [all ]

Toolbar's show() and hide() method do not properly toggle items visibility in the overflow popup.

Case 1: https://dojo.telerik.com/aXEyIrEW/6

The 'Button' is visible in both the Toolbar and the overflow popup initially.

Case 2: https://dojo.telerik.com/erEnafir/39

When the Toolbar is resized so that the 'Dashboard' button is not visible, the 'Dashboard' button is also not visible in the overflow popup.

Hello,

Buttons and button groups support badges only if they are "standing alone". If buttons or button groups are part of a toolbar item collection, badge system is not working/implemented. I don't see any reason why this feature would be missing from toolbar items unless it was maybe overlooked :) For the sake of consistency and usability I think toolbar items (at least buttons) should behave the same across.

Demo: https://dojo.telerik.com/enOSuxEw/4
