Phil1234 what actions would you like to perform on multiple discussions at once?
Flarum doesn't have a built-in concept for mass action, but an extension could call an API endpoint in a loop based on a list of selected discussions.
It might be a bit tricky to implement support for actions added by community extensions, because not all actions might be available on all discussions and not all actions are just an API call. Creating such an extension would probably require hard-coding each supported mass-action.
