Dynamic Fields

The process of defining dynamic fields includes two steps:

1. Create a dynamic field definition, which mainly contains information related to dynamic field storage, such as data type, optional items, etc.
2. Create a dynamic field instance, which mainly contains information related to the display of dynamic fields, such as display name, display control type, etc.

The system supports creating dynamic field instances in the following scenarios to transfer and save data between the front and back ends:

• Create dynamic fields associated with a certain Action to display parameter input forms and pass parameters when executing the Action.
• Create dynamic fields associated with a certain Wizard to display parameter input forms and pass parameters when displaying the wizard form.
• Create dynamic fields associated with a certain Domain Instance to control the attribute list of object instances through a certain type.

Multiple dynamic field instances can be associated with the same dynamic field definition.

Creating Dynamic Fields

The system supports direct creation of dynamic fields through interface operations. The specific steps are as follows:

• On the interface, log in to the system using a developer account (default system is [email protected]), create a Dynamic Field Definition definition, as shown below:

• By creating an Dynamic Field Instance object, associate the newly created dynamic field with a certain action or wizard, so that the system will display this field when run an action or wizard.

The currently supported dynamic field and interface display control types are described as follows:

Data Type	Description	Display Controls
STRING	Character	Long text input box
		Single-line character input box
		Multiple selection input box
		Single selection input box
		Single selection or input Not implemented
		Multiple selection or input Not implemented

		Single selection input box
		Single selection or input Not implemented
		Multiple selection or input Not implemented

		Percentage
		Currency
BOOLEAN	Boolean	Switch
FILE	Attachment	Single file upload
		Multiple file upload
IMAGE	Image	Single image upload and preview
		Multiple image upload and preview
OBJECT	Object association	Associate with one object
		Associate with multiple objects

System Limitation

Currently in the system, for currency types, the displayed currency symbol is always $, multi-language support has not been implemented yet.

Dynamic fields can also be created through CSV import.

Setting Field Options

The options for selection fields are set through the options JSON field when creating a Dynamic Field Definition. After setting, all available options will be saved in the system in the form of a JSON string.

Action and Wizard Field Customization Support

Action and Wizard fields also support customization using fieldhook, setting default values, field cascading, visibility, etc. For specific information, please refer to the Action and Wizard Field Customization section.
