Hi @essi1990, this message is the placeholder attribute of an input (as you can see from inspecting the element in your browser), That said, there is no easy way to change the content through CSS, so you would probably have to do this through some Javascript code…
It would have been nice if there was a placeholder attribute or a hover info attribute (just like the normal cells in DataTable). I’m trying to put an instruction instead of “filter data…” for a more user-friendly filtering!
