The multi column combo box is great to show users some more details (and it looks better than simple select fields).
Feature request: Add option "multiSelect: boolean"
Expected behavior:
* Users can select multiple values
* Selected values are visualized as chips (same behavior as existing MultiSelect component)
* To select an item, users open the dropdown multiple times and select one item to add to list of selected items
Currently, the columns of the MultiColumnComboBox do not support built-in functionalities for user manipulation like sorting, resizing, etc., similar to the Grid component for example. The only available approach for achieving this is by implementing a Grid component in the popup of a ComboBox component through a template:
Please provide the ability to sort, resize, etc. the columns of the MultiColumnComboBox.
In MultiColumnComboBox .k-table-header-wrap sets extra border-right-width, in result cells and column vertical separator is not consistent.
