Types of filter

The ChoiceRenderer is a generic renderer for a number of filter style renderers, such as checkboxes, radiobuttons, and dropdowns. The ChoiceRenderer delegates to a specific renderer depending on what displayType is selected by the ChoiceBuilder.

The table below lists the existing filter renderers. The type and displayType combine to select a specific renderer.
