Bootstrap datatable with multi select check box and multi search box

I already use Bootstrap5 for datatable search and sort. I wanted to upgrade it to include multi row select check box (and submit button) and multi column search (not one common search box but multiple column search boxes). I have Bootstrap link where JS, CSS and sample HTML is available, I need help to integrate this code fully in my project. I want to send multi column selection submit button to send data back to my Flask server. I will pay only when code can be fully integrated.
