Hidden Component
Overview
The Hidden component component acts as a holding place for any data type or data structure in your application. This data can include numbers, objects, arrays, or arrays of objects. This flexibility makes the Hidden component perfect for storing data.
Hidden components are only visible in the Module Builder. Being invisible to 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.s makes Hidden components great for storing and passing in information behind the scenes.
A few scenarios lend themselves particularly well to using Hidden components. You can use them to support interactions with logic and data-type components: Calculators, Decisions, Initializers, and Data Workflows. For example, saving the id or exportId values of a ViewGrid row to a Hidden component. After saving, you can reference that row using a logic component. After saving this value, you can reference the module ID in a Plug-In component's Get Submissions call. To avoid hard-coding the module ID in a Plug-In, you can reference the Hidden component instead. Hidden components offer a simplified approach to setting the default value. Other components (for example, Text Field components) need an Initializer component to work.
It's important to note that you should always use Hidden components when storing non-primitive data types, like arrays and objects. Using other components to store non-primitives, like an array in a Text Field component, can lead to unpredictable and non-deterministic behavior.
You'll find the component under the Secondary Fields group to the left of the Module Builder.
What You'll Learn
After completing this article, you’ll know when to use a Hidden component, how to configure its settings, and how to use it in an Unqork application.

Label Text |
A component’s Canvas Label Text indicates the purpose of the corresponding field or component. For non-input components, the Canvas Label Text isn't end-user facing, and only appears in the Module Builder. 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. |

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. 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. |

Default Value |
Enter a value to store in the Hidden component by default. Using a Default Value is a simple way to define and store data, which you can then reference in another component. For example, defining a specific module ID to reference in a Plug-In’s Get Submissions call. You can still pass values into the Hidden component to overwrite the Default Value. The Hidden component can only store Default Values as strings. |

Adding a Hidden Component
Let's add a Hidden component as the output of a Data Workflow. These instructions assume that you have an open module saved with a title.
| 1. | In the Module Builder, drag and drop a Hidden component onto your canvas. |
| 2. | In the Property ID A Property ID is the unique field ID used by Unqork to track and link components in your module. field, enter dwfOutput. |
| 4. | Click Save Component. |
| 5. | Save your module. |
Now that you've configured your Hidden component, use it as an output for your Data Workflow. For more information, see the Data Workflow component article in our Documentation Hub.
Because the Hidden component is hidden from the end-user, it doesn't in Express View Express View is how your end-user views your application. Express View also lets you preview your applications to test your configuration and view the styling. This is also the view your end-users will see when interacting with your application. After configuring a module, click Preview in the Module Builder to interact with the module in Express View.. However, you can use the angular command in Express View to see the Hidden component data.
