Container AtrributeError

[kXborg]

Hi,

Thanks to your beautiful video on ft_db_search in YouTube. It was really helpful. I have been working on selection of dropdown values and displaying a container below the text field.

Code Here

As you can see, I have added a method to display the relevant data corresponding to the selection. However, it is showing the following error.

AttributeError: 'list' object has no attribute '_set_attr_internal'

Detailed Error Below
