# Widgets
Material constructors live under `material::widget`. The root file is the shared
constructor entry point; larger or stateful components are grouped into focused
modules.
## Layout and App Structure
- `page` provides page surfaces, headers, sections, rows, stacks, and common
showcase-style layout helpers.
- `navigation` provides destinations, adaptive navigation state, bottom
navigation bar, rail, drawer, and the `suite` builder.
- `app_bar`, `toolbar`, `sheet`, `dialog`, `snackbar`, and `viewport` provide
higher-level structure and overlays.
## Inputs
- `text_input` provides Material text fields.
- `text_editor` provides multi-line text editor constructors.
- `select` and `combobox` provide selection fields.
- `picker` provides date picker, date range picker, time picker, time input, and
time scroll state.
- `search` provides search bar and search view helpers.
## Actions and Selection Controls
- `button` provides elevated, filled, tonal, outlined, text, icon, FAB, extended
FAB, and chip constructors.
- `checkbox`, `radio`, `slider`, `segmented_button`, `tabs`, and `toggler`
provide Material-sized selection controls.
## Feedback and Data Display
- `progress_bar` provides determinate and indeterminate progress indicators.
- `badge`, `tooltip`, `card`, `list`, `data_table`, and `rule` provide common
display components.
- `theme_picker` provides a floating Material color picker and animated theme
reveal helpers.
## Pattern
The constructors set Material metrics such as height, padding, shape, typography,
and icon size. Colors and visual states are still resolved by the style catalogs
for `Theme`.
```rust
material::widget::button::filled("Save").on_press(Message::Save);
material::widget::text_input::outlined("Name", &state.name).on_input(Message::NameChanged);
```
