Hello, Hubert,

Thank you for the detailed report - we are aware of this behavior and it is already logged in our internal repo.

When `filterable={true}` is set, the DropDownList's internal keyboard handler intercepts Home and End key events on the filter input and calls `preventDefault`, which prevents the browser from executing the default cursor movement. Left and Right arrow keys are correctly excluded from this interception in filterable mode, but Home and End are not, so cursor navigation to the start or end of the filter text does not work. Shift+Home and Shift+End (text selection) are affected for the same reason.

For convenience, I created a public issue mirroring the internal one, so you can track its progress there:

• https://github.com/telerik/kendo-react-private/issues/7987 

Until the fix is released, a DOM-level capture listener can be attached to the filter input to intercept Home/End before the component's internal handler runs. Use `popupSettings.popupClass` to uniquely identify the popup and avoid affecting other components on the page:

Please, accept our apologies for the inconveniences caused by this bug.
