Hello, although I have searched quite a bit, have not found anything yet to my little problem. First of all: I read a few comments in a separate overview page, the table with the information I created this using "WP_List_Table", and I use "get_bulk_actions" to place a dropdown-menubox for delete, edit and so on.
Now I would like next to this dropdown box to add, however, another box to filter comments e.g. from "2012", "2013", "2014" and so on. Question: How can I add a second drop-down box of the "WP_List_Table" anyone here?
