Bug report

When the selectable option is set to "multiple cell" and the user tries to select the content of a single column, the content of the entire row is selected.

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/@NeliK/AzirANuT
2. Try to select the text in the France cell and drag down to select only the content in the ShipCountry column.

Current behavior

The content of the other columns is selected as well - https://somup.com/cZeXIvpRzk

Expected/desired behavior

The behavior is expected when the allowPaste option is enabled. However, once the allowPaste option is disabled only the content of the selected column should be selected.

Workaround

kendo.ui.Selectable.fn._allowPreventDefault = () => true;
Dojo - https://dojo.telerik.com/@NeliK/eTocoBOL

Environment

• Kendo UI version: 2024.1.130
• jQuery version: x.y
• Browser: [all ]

In cases when we have loadOnDemand set to true and we want to populate the value of the DropDownTree initially we need a way to check if this value is part of the available options. One possible solution is adding a valueMapper function similar to the one use in virtualization scenarios.
