The component creates ToolbarFilter and ChipGroup components from
provided data which may be dynamic. It may happen that the created
components have the same keys as other filters created manually.

Provided unique keys are built by concatenating category title and
group name. The category title is known at compile time and is expected
to be unique. Group name is calculated from the provided data. Each
group results in new ToolbarFilter/ChipGroup
