not displaying widget by category

This is the solution I think I need.

so, in “your widget title” –> Do I have to put “Info Canada”? Info canada is the name of the menu I want to put in the left sidebar only for the posts with the category Canada

1 function custom_rw_display_widget ($display, $instance) {
2 if (is_category(1) && $instance[‘title’] == ‘Your widget title’) { // change Your widget title
3 $display = true; // or false if you want to hide it
4 }
5 return $display;
6 }
7 add_filter(‘rw_display_widget’, ‘custom_rw_display_widget’, 10, 2);

That’s the right direction.

‘Your widget title’ is the title of the widget, no matter what kind of widget it is.

is_category(1) – 1, is the number of category, so you have to find the ID of Canada category and use it in the code snippet above
