Widget Functionality

What it does

Renders a dropdown for selecting a value (e.g., a station id or variable path). The selection is published to the dashboard context so other widgets can filter/target accordingly.

Expected input

• values: the list of items to present; strings are rendered as labels by default.

• allowedVars (optional): constrain which variables the widget is allowed to publish/target when used alongside variable-aware widgets.

Integration

• No GraphQL calls are made by this widget.

• The currently selected value is emitted via the Widget SDK context, making it easy to wire to other widgets’ props or to global filters.

What you’ll see

• A compact dropdown listing your values.

• On change, dependent widgets update (e.g., graphs switch to the selected station).
