Dropdown Component

Prev Next

Overview

The Dropdown component enables your end-user to select a single option from a list. Use the Dropdown component in situations where lists contain too many options for Radio Buttons and Checkboxes components. For example, use a Dropdown component if you have six or more options, or you don't want the full list of options to display on the page at all times.

By default, the Dropdown component stays collapsed until the end-user clicks to open it. After making a selection, the Dropdown list closes again. Your end-user has the option to type the first few letters of their response to quickly find that option in the list.

The Dropdown component is located in the Primary Fields group to the left of the Module Builder.

Setting

Description

Store Data in Database

The Store Data in Database setting affects how data persists through your application. When set to A toggle switch indicating an on/off state for a user interface element. (ON), Unqork stores values entered into the field to the database (server-side submission). This occurs in three scenarios:

  • Navigating between Panels in a Navigation component. On navigation between pages (Panels), the component’s value saves to the database.

  • Triggering a module save event using a Button component with an Action Type of Save.

  • Navigating between screens of a workflow. On navigation between screens, the component’s value saves to the database.

    By default, workflows persist data from all fields in the client-side submission when navigating between screens. However, only values from fields with Store Data in Database enabled store in the server-side submission.

Set the toggle to A toggle switch in the 'on' position, indicating an active setting or feature. (OFF) when you don’t want to store the values from this field in the database.

When using a Plug-In to remote execute a module, ensure data moving between modules is persistent. You can optionally enable Store Data in Database for components in the source module. But any components in the API module whose values are included in an API response must have Store Data in Database enabled. When a component’s data is not persistent, the data isn't included in an API call's response. So, Plug-Ins or external services requesting data from the API module can't receive non-persistent data in the response.

Store Data in Database also affects what data is tracked using Unqork’s built-in tracker. When the Enable Tracker and Track Value toggles are set to A toggle switch indicating an on/off state for a user interface element. (ON) in Module Settings, only values from fields with Store Data in Database enabled are tracked.

Data Source Type

There are three methods that you can use to populate a Dropdown component: Values, URL, and Data Reference Key.

Values

Selecting Values displays a table where you can enter each option and its value.

A static image displaying the Udesigner Dropdown component's Values Data Source Type.

Setting

Description

Option Label                                                                        

Each option needs an end-user-facing label describing the choice that it represents. Enter your Option Labels using this column.

After you create an option, another row displays for you to create the next option.

Data Source Values                                                                        

Each option needs an associated value to store in the submission data. Enter the values to store in submission data using this column.

By default, the value is a camel case version of the Option Label. You can also assign a numeric value to each option for use in logic-based configurations.

In Express View, the dropdown list searches and filters using the Option Label and Data Source values.

URL

To use data that are not stored in a specific component, select URL. Generally, this data lives in two places:

  • External to Unqork and pulled into the component using an external API call.

  • Internally and stored as a data collection.

To use an external API call, reference the provider's documentation. There, you'll find the API's URL address and the information you need to filter the data. To learn more, see our Using an External API in a Dropdown Component article.

To reference data collections in Unqork, use the Data Collection Icon Data Collections tab at the Application Level. Click Create Data Collection to create a new data collection. Or, look through the available data collections and use one of those.

To learn more data collectioins, see our Workspaces: Data Collections article.

Setting

Description

Request Header                                                                        

Enter the information to display in the drop-down selections. These are your end-user's options. For external APIs, you'll find this information in the API documentation. To pull data from a Data Collection, enter the column header you want to use.

Option Value                                                                        

Each option needs an associated value to store in the submission data. Enter the values to store in submission data using this column.

By default, the value is a camel case version of the Option Label. You can also assign a numeric value to each option for use in logic-based configurations.

Data Source URL                                                                        

For an API to retrieve data, you need the API's URL information. In this field, enter the API information as obtained from the API documentation. Add additional filters at the end of the URL if you want to drill down to a specific type of data.

Data Path                                                                        

If using an API call to populate the component, enter a specific data property to reference here. This is useful if you want to show one piece of a larger data set in your Dropdown component.

Filter Query                                                                        

Provide additional filtering using query parameters. Parameters append to the end of the Data Source URL. Query parameters can be static or dynamic. For example, name={{data.groupName}}.

Value Property                                                                        

If a data set includes a column for values, enter the column's name here.

If not specified, the application uses the option label itself.

Label Path                                                                        

This field refers to the option labels you want to pull. Enter the option label's column header in this field.

Refresh On                                                                        

This field displays a list of the other components in your module. You can select a component here to refresh your Dropdown. When your end-user interacts with the selected component, the Dropdown resets.

You can also select Any Change. This refreshes the Dropdown if your end-user interacts with any of your components.

This setting watches other components in your module. The more components the component watches, the more performance issues can occur. It’s also important to note that processes large amounts of data on the client side will also impact performance.

Require Search Parameters                                                                        

When set to A toggle switch indicating an on/off state for a user interface element. (ON), search parameters must be present to execute the search.

Authenticate                                                                        

When set to A toggle switch indicating an on/off state for a user interface element. (ON), authentication headers from the application are sent to the Data Source URL destination.

By default, this setting is A toggle switch in the 'on' position, indicating an active setting or feature. (OFF).

Data Reference Key

Using the Data Reference Key option, data from another component populates the Dropdown component. You'll most often do this with a Data Table component. Add your data to the Data Table. Then, reference the Data Table in your Dropdown's configuration window.

Think of this as a hybrid option of using Values and Data Collections to populate your Dropdown. You still use data stored in Unqork, but it's data from your module instead of a Data Collection.

Data Storage

Setting

Description

Store Data in Database

The Store Data in Database setting affects how data persists through your application. When set to A toggle switch indicating an on/off state for a user interface element. (ON), Unqork stores values entered into the field to the database (server-side submission). This occurs in three scenarios:

  • Navigating between Panels in a Navigation component. On navigation between pages (Panels), the component’s value saves to the database.

  • Triggering a module save event using a Button component with an Action Type of Save.

  • Navigating between screens of a workflow. On navigation between screens, the component’s value saves to the database.

    By default, workflows persist data from all fields in the client-side submission when navigating between screens. However, only values from fields with Store Data in Database enabled store in the server-side submission.

Set the toggle to A toggle switch in the 'on' position, indicating an active setting or feature. (OFF) when you don’t want to store the values from this field in the database.

When using a Plug-In to remote execute a module, ensure data moving between modules is persistent. You can optionally enable Store Data in Database for components in the source module. But any components in the API module whose values are included in an API response must have Store Data in Database enabled. When a component’s data is not persistent, the data isn't included in an API call's response. So, Plug-Ins or external services requesting data from the API module can't receive non-persistent data in the response.

Store Data in Database also affects what data is tracked using Unqork’s built-in tracker. When the Enable Tracker and Track Value toggles are set to A toggle switch indicating an on/off state for a user interface element. (ON) in Module Settings, only values from fields with Store Data in Database enabled are tracked.
