        label: "option1",
        value: 1,
        disable: false,

      },
      { 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:

{
  {
    queries.getEmployees.data.map((option) => ({
      label: option.firstname,
      value: option.firstname,
      disable: false,
      visible: true,

  }
}

:::info Check Action Reference docs to get detailed information about all the Actions. :::

Component specific actions (CSA)

The following actions of the component can be controlled using the component-specific actions (CSA), you can trigger it using an event or use a RunJS query.

<div style={{ width:"100px"}}> Actions	<div style={{ width:"160px"}}> Description	<div style={{width: "200px"}}> How To Access
clear( )	Clears the selected option.	components.dropdown1.clear()
setVisibility( )	Sets the visibility of the component.	components.dropdown1.setVisibility(false)
setLoading( )	Sets the loading state of the component.	components.dropdown1.setLoading(true)
setDisable( )	Disables the component.	components.dropdown1.setDisable(true)
selectOption( )	Selects an option.	components.dropdown1.selectOption(2)

Note: The data type passed to CSAs like selectOption() depends on how you configure the component. When adding options manually using the Add new option button, values must be strings (for example, components.dropdown1.selectOption(['2'])). When using dynamic options, supply values with the correct data types as they appear in your code logic.

For example, if the code is:

{
  {
    [
      {
        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 },
    ];
  }
}

You should pass numeric values in the selectOption component-specific action since the value type is Number:

components.dropdown1.selectOption(2);
