Static input fields

Actions/Triggers in plugins require an input form because they always need a way for users to send data to your app’s API to find, update, or create a new object. Syntax to create static type fields through JSON are as follow: 

Static Input Fields
Static input fields are predefined and do not change based on user interactions. They are essential components in forms and user interfaces for collecting and displaying specific types of data. Here's an overview of different static input field types and their functions: 

String
​A string input field collects text data, such as names, addresses, and email addresses. For example, a field labeled "Name" might guide users with an initial value like "John Doe."

Number
A number input field collects numerical data, ideal for ages, quantities, or prices. It ensures users enter valid numbers and can enforce constraints like minimum and maximum values.

Boolean
Boolean input fields capture binary choices (true/false, yes/no) using checkboxes or toggles. They are useful for preferences like agreeing to terms or subscribing to newsletters.

Static Dropdown
Static dropdown fields provide a fixed list of options, ensuring consistent data entry. They are ideal for selections like country or status, offering users a predefined list to choose from.

Input Group
Input groups are collections of related input fields under one label, useful for capturing complex data like addresses or contact information. They help organize related data, making forms more user-friendly.

Default
The default value sets the initial content of an input field, providing users with a hint or example of the expected input. This improves form usability and ensures data consistency.
