The issue is reproducible when the `AllowCustom` parameter is set to `true`.
Typing rapidly in the input field of the MultiColumnComboBox component causes the entered text to blink. Also, some of the inserted symbols are cleared.

Reproduction (if bug)

Open this demo: https://demos.telerik.com/blazor-ui/multicolumncombobox/custom-values

Try to input text rapidly into the input field.

Currently, only the TextField is taken into account when filtering. It would be extremely helpful if other fields besides the TextField could also be included in the filter.

Admin Edit:

This feature request is only for filtering via the component input. For filtering via the column interface and other Grid-like features, please refer to this feature request.

I was wondering if the component can filter rows by searching in more than one column.

from this screenshot from the demo selecting a value via the keyboard leaves the box blank

Hello

I have a  large dataset. I would like to load data only when  i open dropdown. Is this possible?

In the MultiColumnComboBox with the Data parameter, filtering and having only one element in the popup results in the popup closing when Tab is pressed, and the item is selected.

This behavior is not replicated in the MultiColumnComboBox with OnRead.

Hello ,

i was wondering if there is an OnSelect event. I would to prevent an item from selection under some conditions

When the MultiColumnComboBox columns are rendered with a foreach loop, the component doesn't remove columns that are no longer defined.

The workaround is to recreate the MultiColumnComboBox: https://blazorrepl.telerik.com/wSOIvzvR46lEZrwy43
