When implementing a custom filter cell (e.g., to support DatePicker modes such as time-only, date-only, or datetime), there is currently no straightforward way to reuse the built-in filter UI elements like the operator selector and clear button.

At the moment, these controls must be recreated manually to match the behavior and styling of the default Grid filter cells. While GridCustomFilterCellProps.children does include these elements, they are bundled together with the default filter input, making it difficult to extract and reuse only the needed parts.

It would be very helpful if the default operator dropdown and clear button were exposed separately (or made easily accessible), so they can be reused in custom filter cells.

This would:

• Ensure visual and behavioral consistency with built-in filter cells

• Reduce duplication of logic and styling

• Minimize the risk of breaking changes when internal class names or implementations are updated

A supported way to access or compose these default controls would greatly improve the developer experience when building custom filter cells.
