Custom filtering and row selection

Hello, I have couple questions regarding crud with bootstrap v4 community.

  • Is there any known way to add custom filter button? For example: when clicked, show rows where column is not null?
  • Bootstrap theme has multiple selection for delete funcionality. How can I get these selected rows to make my own funcionality with PHP. For example: I get email adresses from selected rows and send emails to these. Is it possible?

Thank you.

I don’t see exactly what you are trying to do…
GC is only a CRUD it’s used as a CRUD, if you want specific functions, just add them in your code.
