Dropdown Component
Overview
The Dropdown component enables your end-user End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product. 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.
What You'll Learn
In this article, you'll learn about the Dropdown component, how to configure its settings, and how to use it in an application.

Label Text |
Label Text conveys what the input component is and what information it displays. Enter the purpose of the corresponding component or field. User-friendly labels make your module more accessible. Keep labels short and descriptive (a word or two) using title case. For longer entries, use sentence case. |
|
Placeholder Text |
A short prompt telling end-users the expected value of an input field. For example: Enter your Social Security Number. Placeholder Text displays inside the input field until the end-user begins an entry. |

Disable User Input |
When set to (ON), end-users cannot interact with or edit the Express View's input field or element. When end-users hover over the field, their cursor changes to alert them to the status change. By default, the Disable User Input toggle is set to (OFF). |
|
Read Only View |
When set to (ON), the component is display-only. If another component sends content to the field, the end-user can view that content. Otherwise, end-users see the word None. By default, the Read Only View toggle is set to (OFF). |
|
Hide Field |
Shows or hides the component from view. Setting the Hide Field toggle to (ON) hides the component in Express View. Setting the toggle to (OFF) shows the component. The component is always visible in the Module Builder. By default, the Hide Field toggle is set to (OFF). |

Store Data in Database |
The Store Data in Database setting affects how data persists through your application. When set to (ON), Unqork stores values entered into the field to the database (server-side submission). This occurs in three scenarios:
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 (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. To learn more about Store Data in Database in the context of API modules, see the panelResponse Panel section of the API Specification Snippet article in our In-Product Help. 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 (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.
|

|
Option Label |
Each option needs an end-user End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product.-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 Also known as Record Data. Submission data consists of information saved by Unqork components. View submission data by using the angular command, or in Record Collections.. Enter the values to store in submission data using this column. By default, the value is a camel case A naming convention for computer programming. Use camelCase for Property IDs, for example: newUser, lastName, & rdoButton. 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 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: Working with Reference Data article.

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. |

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. |

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.
