Class Usage

Here's how to create an instance of the RadioButtonElement class:

Java

OptionElement option1 = new OptionElement("Option1", "1");
OptionElement option2 = new OptionElement("Option2", "2");
List<OptionElement> optionElementList = new ArrayList<>();
optionElementList.add(option1);
optionElementList.add(option2);

RadioButtonElement radioButtonElement = new RadioButtonElement("idSelect", "Choose an option", optionElementList);

In this example, a new instance of RadioButtonElement is created with an elementId "idSelect", a label "Choose an option", and a list of two options.

Default Value of the Input Element

The setDefaultValue() method sets the default value in the single select input, while the getDefaultValue() retrieves it.

For example:

Java

Example

Here is an example that showcases the creation and manipulation of an instance of SingleSelectElement:

Java

OptionElement option1 = new OptionElement("Option1", "1");
OptionElement option2 = new OptionElement("Option2", "2");
List<OptionElement> optionElementList = new ArrayList<>();
optionElementList.add(option1);
optionElementList.add(option2);

// Create a new instance of SingleSelectElement
RadioButtonElement radioButtonElement = new SingleSelectElement("1", "Choose an option", optionsList);

// Set and get the default value
radioButtonElement.setDefaultValue("1");
