The **Radio button** component can be used to collect user input from a list of options.

## Data

| <div style={{ width:"100px"}}> Property </div> | <div style={{ width:"250px"}}> Description </div> | <div style={{width: "200px"}}> Expected Value </div>|
|:---------------|:-------------------------------------------------|:-----------------------------|
| Label         | Text to display as the label for the component.           | String (e.g., `Select an option`).         |

## Options
Allows you to add options to the radio button field. You can click on `Add new option` and add options manually or enable `Dynamic options` and enter the options using code. 

### Example Code for Dynamic Columns

1. Passing an array of objects and specifying each value:

```js
{{
    [{label: 'option1', value: 1, disable: false, visible: true, default: true},
    {label: 'option2', value: 2, disable: false, visible: true},
    {label: 'option3', value: 3, disable: false, visible: true}]
}}
```

2. Passing an array of objects with a default value from a **Table** component's selected row:

```js
{{
    queries.getEmployees.data.map(option => ({
    label: option.firstname,
    value: option.firstname,
    disable: false,
    visible: true,
    default: option.firstname === components.table1.selectedRow.firstname 
    }))
}} 
```

### Options loading state
Allows you to add a loading state to the dynamically generated options. You can enable or disable the toggle button or dynamically configure the value by clicking on **fx** and entering a logical expression.

## Component specific actions (CSA)

Following actions of the component can be controlled using the component specific actions(CSA):

| :------------ | :---------- | :------------ |
| clear()        | Clears the selected option.      | Employ a RunJS query (for e.g.,  <br/> `await components.radiobutton1.clear()`) or trigger it using an event. |
| setVisibility()| Sets the visibility of the component.            | Employ a RunJS query (for e.g.,  <br/> `await components.radiobutton1.setVisibility(false)`) or trigger it using an event. |
| setLoading()   | Sets the loading state of the component.         | Employ a RunJS query (for e.g.,  <br/> `await components.radiobutton1.setLoading(true)`) or trigger it using an event. |

| selectOption()        | Selects an option.      | Employ a RunJS query (for e.g.,  <br/> `await components.radiobutton1.selectOption(2)`) or trigger it using an event. |
