Advanced Team View Filters

Team View Filters allow supervisors to search or filter their agents by name or activity. You can also use custom, programmatically defined filter criteria, like teams or skills. This page describes the main concepts involved in customizing Team View Filters, and includes some sample code you can use to get started with the feature. For more information about using Team View Filters, check out the End User Guide!

This feature is in pilot between version 1.18 and version 1.26.3 of the Flex UI. You can enable team view filters on the pre-release features page within Flex Admin. This feature is enabled by default for version 1.27.0 and upper.

Key Concepts

Flex uses the following objects and components to generate Team View Filters:


The portion of the Flex UI that shows the Team Filters. It is a child component of the Supervisor UI. By default, Flex allows you to filter by agent Activity, but you can add custom filters to the panel by modifying the defaultProps, like so:

Flex.TeamsView.defaultProps.filters = [
    // ... custom filters here


A FilterDefinition is a structure that tells Flex how to render the new filter label and field, and what to query the field value against. Each field will add a new condition to the Sync query that will render the agents (or workers) list to the UI. A FilterDefinition has the following structure:

interface FilterDefinition {
   id: string;
   title: React.ReactChild;
   fieldName: string;
   type?: FiltersListItemType;
   options?: Array;
   customStructure?: CustomFilterItemStructure;
   condition?: string;
Field Description

Required. A string representing the subject of your query. This identifies the values to filter for in the Flex app state based on your specified attribute or field. For example, "data.attributes.full_name" or "data.activity_name".

title Required. A string that is rendered as the filter display name on the Filters side panel. For example, "Names".

Required. A string representing the input name passed to the predefined filters. For example, "full_name".

type Required if customStructure isn't defined. Currently only supports "multiValue". This renders a list of checkboxes for each option you provide.
options Required if type is "multiValue". An array of filter definition options used for rendering the checkbox fields, their values, their labels, and whether they are selected by default.
customStructure Required if type isn't set. An object of type CustomFilterItemStructure used for rendering custom fields. This lets you add your own custom fields.

An optional parameter that represents the query comparison operator such as IN, NOT_IN, CONTAINS. See Query Operators to learn about other possible condition values.

This represents the condition to be used in building the query. For instance, data.activity_name IN ["available"] or data.attributes.full_name CONTAINS "John". In the latter example, "data.attributes.full_name" is the id, "CONTAINS" is the condition, and "John" is the value to filter for.


Describes the available options which can be used as a filter. For example, if you wanted to filter by agent languages, you could create an option for each language spoken in your contact center.

interface FilterDefinitionOption {
   value: string;
   label: string;
   default?: boolean;
Field Description

Value of the filter option. When using IN or NOT_IN to build your query and you are providing an array of options, you need to omit the first and the last instances of double quotes in your string. See example in Add a multivalue field

label Friendly name of the option.
default A boolean value indicating whether the filter option should be selected by default.


To add a custom field and label to a filter, you'll need an object with a select field or an input field passed to the CustomFilterItemStructure.

interface CustomFilterItemStructure {
   field: React.ReactElement;
   label: React.ReactElement;

field is a React element that should render an input usable by the final customer. It inherits a few custom props from Flex.

Field Description
name The field name set in the FilterDefinition.
handleChange A function that gets invoked on this custom field change event. It requires the new value of the filter to be passed as an argument, either as an array of strings or a string.
options The same options passed in the FilterDefinition, if provided.
currentValue The current value of the filter. It can either be an array of strings or a string, depending on what the props.handleChange function receives once invoked.

label is another React element that serves as the label of the filter. It should indicate the content of the filter when the accordion item is closed. It receives the following properties:

Field Description
currentValue The current value of the filter.
activeOption is the options array that is provided and returns the entire selected option. It will contain currentValue as value.


The filters array also accepts FiltersDefinitionFactories. A FilterDefinitionFactory is a simple function which returns a FilterDefinition. You can write a FilterDefinitionFactory that fetches data from the app state and dynamically renders values or options of a field.

Your factory must accept two arguments:

Argument Description


The entire Flex Redux state. Use this to access information about activities, session, and more details about the current state of your Flex instance.
ownProps The props received by the TeamFiltersPanel.

Customizing your Filters

The TeamFiltersPanel includes activitiesFilter by default. To add a new filter to the TeamsFiltersPanel, you can overwrite the defaultProps.filters property with a new array of filter definitions before rendering your Flex instance.

This array can contain both FilterDefinitions and FilterDefinition factories. In this example, we are readding the default activity filter as the first item of the array.

Flex.TeamsView.defaultProps.filters = [

Add a custom input field

Initially, the FilterDefinition has one predefined type, which will output checkboxes: MultiValue. With custom input fields, you can add a different type of input, like a custom text input field.

The following file describes the HTML for your custom field, as well as the JavaScript associated with its behavior. In this sample, the filter functionality is extended in the extendFilters function

        Add a custom filter

        Add a multivalue field

        The following example will filter by agents located in any of the options specified in the value field:

        import React from "react";
        import { TeamsView } from "@twilio/flex-ui";
        import { FiltersListItemType } from "@twilio/flex-ui";
        // Define a new filter that uses the custom field
        const teamFilter = {
            fieldName: "team_location",
            title: 'Team',
            id: 'data.attributes.squad',
            type: FiltersListItemType.multiValue,
            options: [
                { label: 'Canada', value: 'CAN-1", "CAN-2", "ARC'}
            condition: 'IN',
        // Export a function to be invoked in plugin's main entry-point
        export const extendFilter = (manager) => {
                componentProps: {
                    TeamsView: {
                        filters: [

        Use a filter definition factory

        You can use a filter definition factory to dynamically render the options of the predefined checkboxes fields. For example, you could render the activities that are currently available on in the Flex Redux store.

              Use a custom filter structure with a filter definition factory

              You can use custom filter input components and filter definition factories together. The following code sample dynamically renders the options of a select field from the current Redux store.

                    Enable your new filter

                    Once you've configured your filter(s), you can enable them in Flex manager from within the base Plugin file. In this example, the extendFilters function is imported and passed to the Flex Manager.

                                                  Hidden Filter

                                                  The hidden filter feature is only available in @twilio/flex-ui@1.21.0 and later.

                                                  You can programmatically apply a filter that is hidden from the user, i.e. the user cannot disable it. You could use this feature to restrict supervisors to seeing only their team members on the page. However, note that this is not a security feature. Supervisors still have access to all agent activity using the underlying APIs.

                                                  In the following example, we use live query to set up Team View to only show agents with a specific team_name attribute (you can set user attributes via your SSO provider):

                                                  Flex.TeamsView.defaultProps.hiddenFilter = 'data.attributes.team_name CONTAINS "sales"'
