We have many scenarios where we have to do similar tasks many times.
Scenario1 ) While deleting pages from Admin side. If we have hundreds of pages and wish to delete, one by one deleting takes lot of time. If we have basic option to select multiple pages and in one click delete all, can be best.
Scenarios 2) Other bulk action scenarios is Adding modules to page. Right now we can add one by one only. But if option is available to select multiple panes at a time while adding module, can be nice feature.
Scenario 3) Assigning Roles to multiple users. If i have to assign same role to many people at a time, if we have feature to select multiple users and then select a role to assign them and click, then can save lot of time. One by one user editing and assigning role takes time if we have many users.
There can be more scenarios which can be included here which if bulk actions are available can make system more robust to use. I am sure in new versions sooner these may come. But i would like to start with my idea and would like all to put more scenarios which can be helpful to all DNN.
