## Events

<div style={{textAlign: 'center'}}>

</div>

### Event: On select

On select event is triggered when an option is selected.

### Event: On search text changed

This event is triggered whenever the user searches through the options by typing on the dropdown's input box. The corresponding search text will be exposed as `searchText`.

## Properties

<div style={{textAlign: 'center'}}>

</div>

### Label

Set the value of the label in the dropdown. The value can also be set dynamically using JavaScript. For example, set the Label value to `Select the {{components.text1.text}}`

### Default value

Specify the default selected option in the dropdown.

### Option value

The option values correspond to the different options available in the dropdown. Dynamically set the option values based on your query, for example: `{{queries.datasource.data.map(item => item.value)}}`.

### Option labels

The option labels represent the displayed labels for each value in the dropdown list. Dynamically set the option labels based on your query, for example: `{{queries.datasource.data.map(item => item.value)}}`.

### Advanced

Configure the dropdown options and manage them by providing an array of objects as data. You can dynamically generate this data using JavaScript. 

For example:
```json
{{[	{label: 'One',value: 1,disable: false,visible: true},{label: 'Two',value: 2,disable: false,visible: true},{label: 'Three',value: 3,disable: false,visible: true}	]}}
```
Each object in the array should include the following key-value pairs:

| Key | Value |
| --- | ----- |
| label | Option label |
| value | Option value |
| disable | Set to true to disable the option for selection, and false to keep it enabled |
| visible | Set to true to display the option in the dropdown list, and false to hide it |

## Validation
