The select widget, (formerly known as dropdown), enables users to select one input from a predetermined list of permitted options. This document provides information on displaying options in the select widget and explains different properties.

How to use Select Widget

Display options manually

To manually display options in a Select widget, you can use the Options property. The Options property is used to specify the available options for the user to choose from. It allows you to set both the label and value for each item in the dropdown list.

The options must be specified as an array of objects, where each object has two properties: label and value. The label property represents the text that's displayed to the user, while the value property is the actual data that's stored and used in your application. For example:

"label": "Blue",
"value": "BLUE"
"label": "Green",
"value": "GREEN"

Display options dynamically

Instead of creating a predetermined set of options, you can dynamically generate options by fetching data from an API or querying a data source.

A Dropdown Options can be populated from a data source like an API / Query by transforming the incoming data to an array of (label, value). The transformation can be performed using JavaScript. So if the data is an array, it can be transformed using the function.

// is assumed to be an array here
{{ => {
return { label:, value: }

Sample app - Dynamically Add Options to a Select Widget

Set default value in options

The Default Selected Value property in a widget allows you to specify an initial value for the widget when it's first displayed. This is useful for pre-populating the widget or ensuring that a specific option is selected by default. To use this property, set its value to the value of the desired option from the Options property.

"label": "Blue",
"value": "BLUE"
"label": "Green",
"value": "GREEN"

For example, if you want the default value to be Blue, set the Default Selected Value property to BLUE.

Access selected option

These properties allow you to bind your select widget with any other widget in queries or JS objects.

The selectedOptionValue in a Select widget is a value that represents the selected option in a dropdown. It updates when the user selects a new option or the default value changes.


The selectedOptionLabel in a Select widget represents the label of the selected option in a dropdown. This property is used to display the label of the selected option in the widget and is updated whenever the user selects a different option from the dropdown list or if the default label changes.


Server side filtering

The Select widget has the option to configure server-side filtering, where search queries are sent to the back-end, and responses are used to populate options on the Select widget. You can implement server-side filtering of options in the Select widget by using the filterText binding property.

The filterText is a binding property in a Select widget that allows you to implement server-side filtering of options in the dropdown list. When enabling server-side filtering in the widget, please update the default value to contain both label and value in this format {"label":<label>, "value": <value>} if the default value isn't present in the default options.

These are functions that are called when event listeners are triggered in the widget. Use actions to execute tasks based on user events.
