## egui Features Missing In Operad
This section lists egui widget and widget-adjacent features from the sources above that do not currently have an equivalent public Operad visual widget builder. Some lower-level Operad contracts may exist, but they are counted as missing here if customers cannot add the feature with a normal `operad::widgets::*` builder.
Partially covered but not equivalent:
- Text editing: Operad has single-line, multiline, text-area, code-editor, search, password, and selectable-text builders, but still needs richer editor-specific features.
- Forms: Operad now has visual section, row, label, help, validation, error-summary, action-button, and traversal helpers plus form state contracts. It still needs richer field-level composition for multi-step and wizard forms.
- Tooltips: Operad now has `tooltip_box`, hover/focus trigger resolution, timing policy, and a reduced-motion-aware animation preset. It still needs richer cross-overlay coordination for complex nested surfaces.
- Dialogs/modals: Operad now has `modal_dialog`, dialog and overlay state contracts, focus-trap helpers, dismissal policy, and open/dismiss event helpers. It still needs richer multi-dialog composition patterns.
- Drag and drop: Operad now has generic `dnd_drag_source` and `dnd_drop_zone` builders, drag-image policy, accepted/rejected drop-preview helpers, and descriptors/metadata on some complex widgets. It still needs fuller platform adapter coverage.
- Scroll bars: Operad exposes a scrollbar widget, geometry/accessibility helpers, aligned scrollbar options, and a composed `scroll_area_with_bars` helper. It still needs adoption across every complex scrollable widget.
- Panels: Operad has `central_panel`, `side_panel`, `top_panel`, `bottom_panel`,
`left_panel`, `right_panel`, `dock_workspace`, `split_pane`, `scroll_area`,
and generic containers. It still needs richer pane-grid docking and animated
panel collapse behavior.
