SETCHOICEFILTER

Filter the choices in a choice field or classification field.

Description

The SETCHOICEFILTER function allows for dynamic filtering of the choice options on choice fields or classification fields. This function differs from SETCHOICES in that only filters the existing choices. That distinction is important because it allows you to maintain your choice options as choice lists and classification sets with label+value pairs and control the available options from data events without having to completely redefine the options with labels and values. Using SETCHOICEFILTER you can supply the filter to apply and it will keep the label and values already defined on the choice options. The filtering is applied to the value portion of the choices and uses case-insensitive “contains” comparison.

Parameters

field String (required) - The data name for the field

filter String,Array,null (required) - The string or strings to filter choices by

Examples

// Filters the choices in the weather summary field to those that contain 'cat'
SETCHOICEFILTER('weather_summary', 'cat')
// Filters the choices in the weather summary field to those that contain 'cat' or 'dog'
SETCHOICEFILTER('weather_summary', ['cat', 'dog'])
// Unsets any filter previously set by SETCHOICEFILTER and applies no filter
SETCHOICEFILTER('weather_summary', null)
