I've already log an issue on Github -> https://github.com/telerik/kendo-react/issues/1303

Submitting here as it is an important regression with React 18 and ReactDom.createRoot breaking Time picker.

When an item, which has submenu, from the menu dropdown is hovered the submenu appears. But if you click on the hovered item the submenu disappears.

Expected Behaviour

When an item, which has submenu, from the menu dropdown is hovered and then clicked the submenu should stay visible.

MInimal Reproduction

I'm providing a reproduction from Kendo React code examples.

Hi there,

I am attempting to utilise the Kendo React ExcelExport component (and in conjunction Kendo UI Spreadsheet component) to be able to export dynamically generated spreadsheets which can do multi-level nested dropdowns on cells, so that our customers who get our spreadsheets can fill in the cells accurately at the point of entry.

Unfortunately the version of the Excel used for these components doesn't support recent formulas, such as SORT, UNIQUE and FILTER which were ok for our Proof of Concept in Excel (Office365 version) but did not work inside the Kendo components listed above.

Could the Kendo components be upgraded to support the latest features of Excel (at least as far as formulas go), this lack of support is impacting our ability to help our customers do remote data entry without additional overhead.

Another example of  the above (which needed additional debug work) was CONCAT vs CONCATENATE, that caught us out for a bit trying to figure out what it was!

Finally, can we make it so exported spreadsheet "sheets" can be hidden as we need a few "preparation" sheets for our data and would be less confusion if it was not visible to the end users.

Thanks for your support on this matter,

Daniel

StackBlitz example: https://stackblitz.com/edit/react-vg8pu5?file=app/main.jsx

If you have a Form <Field component={Input}> inside an <ExpansionPanel>, if you press space or enter within the input, the expansion panel also receives the key event and will expand/collapse. It seems like these key events should not bubble out of the Field component.

There is an issue with ComboBox remote virtualization.  This is reproducible on https://www.telerik.com/kendo-react-ui/components/dropdowns/combobox/filtering/#toc-filtering-with-remote-data-and-virtualization

Scroll slowly till almost the end of the list. Pay attention to the name: Paula Parente

Notice that the name keeps repeating after scrolling as the scroll goes back and forth. You'll need to scroll a few times more before the scroll continues to load

other items.

in the kendo UI react chart I need the average line, max line, and min line targeting some value   

Please suggest which features to use with respect to the above requirements, if available.

Steps to reproduce:

1. Create a notification and a button to toggle it
2. Run a screen reader such as NVDA or JAWS
   
3. Toggle the notification to appear

Expected result: The text in the notification is read by the screen reader when the notification appears

Actual result: The notification text is not read out

Add support for complex object array filter of DataSourceRequest.

let dataSourceRequestFilterComplexObjectArray = {
  filter: {
    logic: "and",
    filters: [
      {
        field: "users[name]", // OR with dot notation -> "users[someObject].name"
        operator: "eq",
        value: "Bill"
      }
    ]
  }
};

Hi,

I'm trying to validate the file names that are being uploaded using Kendo react Upload component. But the validation message I set is not displaying next to the file just the way the following messages are displayed.

File type not allowed.
Invalid file(s). Please check file upload requirements.
File size too large.
File size too small.

For reproducing the steps here is the code pen. If you try to upload any file which contains 2019 should show the validation error message.

Could you please consider this request as a new feature?

As present in other Kendo suites:

Dropdownbutton doesn't work in FF 66.0.2 on maxOS

1. Click on the dropdownbutton
2. Clicking outside of the dropdownbutton menu
3. The dropdownbutton does not close

I would like to request a new Kendo React Grid column editing option so that users can navigate editable columns using the keyboard. This feature should be similar to "navigatable" option from Kendo jQuery grid example - https://demos.telerik.com/kendo-ui/grid/editing

Thanks.

Set TabStrip items on multiple rows, instead of scrolling.

If there are many items, they should be shown on multiple row.
