I have a drop-down list, with the following options:
Approved
Disapproved
Unread
Read

Data will be searched and retrieved from a database based on the selection of the admin, event-based, meaning every time the selection is changed, the results shown are refreshed according to the criteria set. How can I achieve this?

That's a lot of coding. That you need to figure out on your own.

But here's a tip :
You can make Jquery AJAX[^] call to the server based on your dropdown selection.
And you can refresh your set of collection in success function of the $.Ajax({...}).

On dropdown change event you can get the selected value as this.value. Then pass that data to server side to retrieve the appropriate data related to it using jQuery Ajax. There are many good articles on implementing this using jQuery on CP.

Please refer to some of them here:

I hope this would help you getting started. If you get stuck in somewhere, then please post a new question along with the code which was not working properly for you while working on it.
