+    The 'wayland.windowManager.hyprland' module now supports submap configuration.
+
+    Submaps allow you to create keybind contexts in Hyprland, useful for
+    creating mode-based workflows like resize modes or application launch menus.
+    Configure submaps using the new 'submaps' option:
+
+    wayland.windowManager.hyprland.submaps.resize = {
+      settings = {
+        binde = [
+          ", right, resizeactive, 10 0"
+          ", left, resizeactive, -10 0"
+          ", up, resizeactive, 0 -10"
+          ", down, resizeactive, 0 10"
+        ];
+        bind = [
+          ", escape, submap, reset"
+        ];
+      };
+    };
