Hi, hope you're fine!

I have published a 2024.1 version which (hopefully) fixes the scroll bug.  I also updated the online documentation and generated an offline version of the HTML documentations (you can download it as well).

With this version, using a somewhat "creative" approach, you'll be able to create a scrollable grid like so:

Test code is as follows:

if (!UI.exists("LevelSelectPanel")) {     var _num_levels = 30;     var _columns = 3;          var _panel = new UIPanel("LevelSelectPanel", 500, 200, 500, 500, blue_panel, UI_RELATIVE_TO.MIDDLE_CENTER);     _panel.setTitle("Level Select").setTitleAnchor(UI_RELATIVE_TO.MIDDLE_CENTER);          var _container = new UIGrid("ContainerGrid", 2, 1);     _container.setRowProportions([0.2, 0.8]);     _container.setShowGridOverlay(true);     _container.getCell(1,0).setClipsContent(true);          var _cnt = _container.addToCell(new UIGroup("GridContainer", 0, 0, 500, 1500, red_panel), 1, 0);          var _grid = new UIGrid("LevelsGrid", _num_levels div _columns, _columns);     _grid.setSpacingHorizontal(20).setSpacingVertical(20).setMarginLeft(50).setMarginRight(50).setMarginTop(10).setMarginBottom(10);               for (var _level = 0; _level < _num_levels; _level++) {         var _button = new UIButton("Level"+string(_level+1), 0, 0, 0, 0 , "Level "+string(_level+1), blue_button00, UI_RELATIVE_TO.MIDDLE_CENTER);         _button.setInheritWidth(true).setInheritHeight(true).setCallback(UI_EVENT.LEFT_RELEASE, method({level: _level}, function() {             show_message("You selected level "+string(level+1));         }));         _grid.addToCell(_button, _level div _columns, _level % _columns);     }     _container.addToCell(_cnt, 1, 0);     _cnt.add(_grid);     _panel.add(_container); }  if (keyboard_check(vk_down))    UI.get("ContainerGrid").getCell(1,0).scroll(UI_ORIENTATION.VERTICAL, -1, 5); if (keyboard_check(vk_up))        UI.get("ContainerGrid").getCell(1,0).scroll(UI_ORIENTATION.VERTICAL, 1, 5);

Hope you find it useful!
