CodeIgniter: Add small new feature to existing website.

We have a social media planing platform that allows users to plan their social media posts in advance.
The process involves users adding their social media pages to the platform, one of the features is that if they change their mind they can remove the added profile/pages from the platform. Currently, they can only do this one profile at a time, we would like to add the ability to select multiple profiles (checkmarks) and click on a button to delete the selected profiles and their corresponding planed posts from our platform.

The platform uses CodeIgniter and we can offer access to GitHub and to the DataBase, as well as a live Staging website.
