A Transfer component in a form is a user interface element that allows users to move items between two lists or collections.

It's commonly used to create interactive selections, manage data assignments, or filter content.

Use Case

  1. Assigning items: Allocate tasks, resources, or responsibilities to individuals or groups.
  2. Creating custom lists: Build personalized selections of products, features, or preferences.
  3. Filtering content: Narrow down options based on specific criteria or preferences.
  4. Managing group memberships: Add or remove users from teams or access lists.
  5. Product configuration: Select desired features or components for a product.
  6. Email management: Move emails between folders or categorize them.

      .abc{ // abc is the class name
      background-color: red;
    • Follow the steps mentioned above, under Steps to use the methods for the Page Builder components
    • this.addClassName('transfer_jhg5bttj', 'abc')
  2. this.removeClassName(fields, className)

    this.removeClassName('transfer_jhg5bttj', 'abc')

  3. this.hide(fields)

    var fields= ['transfer_jhg5bttj']

Dynamic data are options fetched as needed from sources like databases or APIs. The transfer updates choices based on user selections. You select from Data source which refers to the origin of the data; Function which refers to the code that manipulates the data, and Assigned Value which refers to the specific value stored or associated with a data element

Attribute Action Enable Data Binding to connect the data to UI.

Enable Disabled action to make the field unusable.


Form validation is the process of checking the data entered into a form to ensure that it's valid and complete.

This helps to prevent users from submitting forms with invalid data, which can cause problems for the application that's processing the form.

Form validation can be performed using a variety of methods, including:

Name Description
Required If enabled, then the field value can't be empty, otherwise an error message is emitted
Custom Validation Rules (rule, value, callback) => {
rule: Verification rule, you can view the verification configuration information through this parameter; rule.field can get the field identifier of the current verification
value: Value of the current field
callback: Callback function (must be called) upon completion of validation; callback('Error message')/ callback(new Error('Error message')). These are two ways to return an error message


  1. The callback() function is also called to verify success in the custom validation method.
