Hi Rashi,
I understand that you want the power value to be selected from the dropdown menu. Therefore, I have created an application that includes a dropdown with several options and a textarea that displays the value chosen using the dropdown. To manage the process of assigning the dropdown's value to the textarea, I have added a callback function to the dropdown.
In short, you can follow the steps below to achieve the desired result:
  1. Add a Drop-Down Component
  2. Configure the Drop-Down Options
  3. Add a Text Area Component
  4. Create a Callback Function for the Drop-Down
  5. Write the Callback Function
  6. Run the App
I am also attaching a screenshot of my app for your reference.
I hope it helps to resolve your issue!
