Is there a way to highlight multiple lines after multiple lines in the sample 08_api → 13_highlight_drag_position?

Hello Seungmin,
You need to use the renderer property to specify the function that will render HTML elements and the filter property to show the HTML elements only for the specific tasks:

Here is an example of how it can be implemented:
