  2. Select and delete all the text in one of the inline editors.
  3. Type any two (or more) characters to reproduce the issue.

Hello,

I have an issue when I use the drag and drop of a picture in the kendo Editor inline.

Let me explain it :

1) Go to : https://runner.telerik.io/fullscreen/uWosAbib (It's the standard example on your site) on chrome 123

2) Select the last editor "Rich UI Widgets for..."

3) Take a file of a picture on your computer and drop it on the first editor "Comprehensive HTML5/..."

Two things :

* The file open on a new tab browser instead of to be added to the html of the first editor

* There is a message in the debug tools (The stack trace is added in the Attach Files)

Uncaught TypeError: Cannot read properties of null (reading 'nodeType')
    at init.index (kendo.all.js:135127:1)

Another element, if you don't select and just drag and drop it's work.

Thank you for your awesome framework and good luck with the correction !

Hi Team,

I would like to request a way to utilize formattingMarks for the Kendo UI Inline Editor without having to set inlineHeight.  The way we use the editor requires its height to grow dynamically as the user types text. We usually have around five editors displayed on the screen at the same time, so it is important for us that formattingMarks works correctly across multiple editors on a single page.

Thank you!

Hi Team,

I would like to request adding visual page breaks with header/footer features.  Comparatively, SyncFusion has this included and it would be great to have Telerik add these features.

Thank you!

### Bug report

A non-breaking space is added at the beginning of each new row when typing in the Editor.  As a result, the method "getRange" returns a wrong "startOffset" index.

### Reproduction of the problem

    1. Subscribe to the "select" event of the Editor;

    2. Log the property "startOffset" of the "getRange" method in the browser console;

    3. Click on any line in the empty Editor and check the logged index. It is "1" instead of "0".

    4. Type in any text in the Editor and click at the beginning of the text - the logged index is "1" instead of "0".

A Dojo sample for reproduction: https://dojo.telerik.com/UqUNoBaM/8

### Expected/desired behavior

The non-breaking space should be removed when typing.

Hi,

 

Bullets are not removed when content is deleted.

  1. Create text editor on a div
  2. Input some text
  3. Make it bold and underline
  4. Make it bulleted
  5. Add few more bullets
  6. Select all bullets
  7. Press backspace

Observe that two bullet points remain

Hi,

 

We are facing an issue as follows.

1. We type some ordered or unordered list and we move cursor one left or right.

2. We do select all and backspace to delete entire list.

 

Issue: First index or bullet never gets deleted does not matter how many times backspace is clicked. On inspecting dom we can see list structure is retained and does not get deleted.

 

Please find attached video.

 

Thanks
