How to change a td elment with a dropdown button [closed]

I'm working on a personal project where I want to use a Checkbox to selected a table row to change the last <td> element by using a Dropdown Button that contains paid, not paid and pending.

Here are some screenshots of the result am driving for.

1. Selected Table

2. Dropdown Button

I hope someone can provide me with some guides in the right direction.
