### Step 1: Create an Input Component

* Create a new Component type Input and check the **`multiline`** checkbox 

### Step 2: Create an Option Selector Component

* Create a new Component type Option Selector and check the **`allow multiple`** checkbox 

### Step 3: Create the computed field

```
function result({
  input,
  option_selector,
  _display_values,
}, { setUserData }) {

  if (!option_selector) return null

  input = (input ? (input + ", ") : "")
    + _display_values.option_selector

  setUserData('input', input)
  setUserData('option_selector', null)

  return result
}
```
