# Wiki widgets

This directory contains the small reusable interaction widgets used by the
wiki. A widget manages an existing DOM structure and its browser interaction;
it does not own wiki or CMap domain rules.

- `ComboBox` filters labelled options and returns their stable values.
- `PopupMenu` positions and dismisses an action menu and provides keyboard
  navigation.
- `TabSet` coordinates tabs, panels and keyboard focus.
- `Tooltip` provides reusable tooltip visibility and placement.
- `DescriptionPreview` composes `Tooltip` with asynchronous wiki-page loading.
- `StatusField` presents persistent or temporary status messages.

Native buttons, inputs, selects and dialogs remain native elements. They do
not get wrapper classes until the application has reusable behaviour for such
a class to own. Functional dialog controllers can therefore be extracted
separately without putting CMap or wiki rules in a generic widget.
