A radio button in an Adaptive Form is a type of input element that allows a user to select one option from a group of related options. It is represented by a small circular button that is either filled or empty to indicate whether the option is selected or not. When a user selects one radio button, the others in the group become deselected. Radio buttons are typically used when there are multiple mutually exclusive options and only one can be selected at a time.
In this example, Options element is used to group the radio buttons together. The Display text element is used to provide a label for an item and Data Value is used to specify the value that is sent to the server when the form is submitted.
Each radio button option has a unique Data value and Display Text attribute. If a user selects the “1-10”, the corresponding Data Value is sent to the server when the form is submitted. This data can then be processed by a server-side script to determine which options were selected by the user, and can be used to perform various actions, such as updating other fields in the form or submitting the form data to a server-side script for further processing.
Additionally, The each radio button can be configured to have different processing values for each option, and this can be set by using Adaptive Forms Rule Editor
There are several reasons to use radio buttons in a form, including:
Limited choices: Radio buttons are used to provide a list of predefined options for the user to choose from, and only one option can be selected at a time. This is useful when the number of options is limited and mutually exclusive.
Clear representation: Radio buttons are clear and easy to understand, making it simple for users to know what they are selecting.
Consistency: Using radio buttons ensures a consistent and standardized way of presenting options to users, making it easier for them to understand and interact with the form.
Easier to use: Radio buttons are easy to use, especially for users who are not familiar with technology, or who have limited mobility.

You can easily customize your Radio button experience for visitors with the Configure Dialog. You can also define Radio button options with ease for a seamless user experience.
Name - You can identify a form component easily with its unique name both in the form and in the rule editor, but the name must not contain spaces or special characters.
Title - With its Title, you can easily identify a component in a form and by default, the title appears on top of the component. If you do not add a title, the name of the component is displayed instead of the title text.
Hide Title - Select the option to hide the component’s Title.
In the Options tab, you can add data values and display text pairs using the Add button. Once a new option is added, the following actions can be performed:
Bind Reference - A bind reference is a reference to a data element that is stored in an external data source and used in a form. The bind reference allows you to dynamically bind data to form fields, so that the form can display the most up-to-date data from the data source. For example, a bind reference can be used to display a customer’s name and address in a form, based on the customer’s ID entered into the form. The bind reference can also be used to update the data source with data entered into the form. In this way, AEM Forms enables you to create forms that interact with external data sources, providing a seamless user experience for collecting and managing data.
Mark as Unbound Form Element: Select the option to configure a form field not linked to any schema. This option allows you to save data without updating the data source. It also enables you to handle data in a custom way, separate from standard database integration.
Data type of submitted value - This option specifies the data type of the value sent when any option is selected. If the data type of submitted value is set to
Number and you add string data to Data Value on the Options tab, the screen displays a
Value type mismatch error message.
Default options - This option allows you to add default values that are pre-selected, when the form loads. If the data type of submitted value is set to
Number and you add string data to Default options, the screen displays a
Value type mismatch error message.
Display options - This option is used to set the visual alignment of radio buttons in an Adaptive Form. The two options supported are:
Hide Component - Select the option to hide the component from the form. The component remains accessible for other purposes, such as using it for calculations in the Rule Editor. This is useful when you need to store information that doesn’t need to be seen or directly changed by the user.
Disable Component - Select the option to disable the component. The disabled component is not active or editable by the end user. The user can see the value of the field but cannot modify it. The component remains accessible for other purposes, such as using it for calculations in the Rule Editor.
Read-only - Select the option to make the component non-editable. The user can see the value of the field but cannot modify it. The component remains accessible for other purposes, such as using it for calculations in the Rule Editor.
Required - Select this option, if you want to display the component in an Adaptive Form. After selecting the option, you must make a selection before proceeding with a form submission. You cannot select the Hide Component or Disable Component in the Basic tab when this option is selected.
Error Message - This option allows you to enter a message that is displayed if the Required checkbox is checked and the form field is left blank.
Script Validation Message - This option allows you to enter a message to be displayed if the script validation fails.
Short description - A short description is a brief text explanation that provides additional information or clarification about the purpose of a specific form field. It helps the user understand what type of data should be entered into the field and can provide guidelines or examples to help ensure that the information entered is valid and meets the desired criteria. By default, short descriptions remain hidden. Enable the Always show short description option to display it below the component.
Always show short description - Enable the option to display the Short description below the component.
Help text - Help text refers to additional information or guidance that is provided to the user to assist them in filling out a form field correctly. It appears when the user clicks the help icon (i) placed next to the component. Help text provides more detailed information than a form field’s label or placeholder text, and is designed to help the user understand the requirements or constraints of the field. It can also offer suggestions or examples to make filling out the form easier and more accurate.
Text for screen readers - Text for screen readers refers to additional text that is specifically intended to be read by assistive technologies, such as screen readers, used by visually impaired individuals. This text provides an audio description of the form field’s purpose, and can include information about the field’s title, description, name, and any relevant messages (Custom text). The screen reader text helps ensure that the form is accessible to all users, including those with visual impairments, and provides them with a complete understanding of the form field and its requirements.
Design Dialog is used to define and manage CSS styles for the Radio button component.
The tab is used to define and manage CSS styles for a component. The Adaptive Forms Radio button Core Component supports the AEM Style System.
Default CSS Classes: You can provide a default CSS class for the Adaptive Forms Checkbox Group Core Component.
Allowed Styles: You can define styles by providing a name and the CSS class that represents the style. For example, you can create a style named “bold text” and provide the CSS class “font-weight: bold”. You can use or apply these styles to an Adaptive Form in Adaptive Forms editor. To apply a style, in Adaptive Forms editor, select the component you want to apply the style to, navigate to the properties dialog, and select the desired style from the Styles drop-down list. If you need to update or modify the styles, simply return to the Design Dialog, update the styles in the styles tab, and save the changes.
Custom properties allows you to associate custom attributes (key-value pairs) to an Adaptive Form core component using the form template. The custom properties are reflected in the properties section of the headless rendition of the component. It allows creating dynamic form behavior that adapts based on the custom attributes values. For example, developers can design various renditions of a Headless Forms component for mobile, desktop, or web platforms, significantly enhancing the user experience across a wide array of devices.
Group Name: You can provide a name to identify the custom property group. You can add, delete, or rearrange multiple custom property groups. After adding the custom property group, you can see the following options:
Key-Value Pairs: You can add multiple custom property names and custom property values by clicking the Add button for each custom property group.
Delete: Tap or click to delete the custom property name and custom property value.
Rearrange: Tap or click and drag to rearrange the order of the custom property name and custom property value.
