I made a custom filter using FilterCellTemplate, now i would like to add filter operator and filter clear button.
For filter clear button it's simple just adding <TelerikButton OnClick="ClearLogic"><span class="k-icon k-i-filter-clear k-button-icon"></TelerikButton>
but how to add filter operator selection?
default filter operator selection is a TelerikDropdownList without span.k-input-inner element, and with k-filter-icon in the button, how can i reply this component? there is one out of the box?
