--- title: Segments description: Show one select filter as a row of buttons. --- `segments(binding, options?)` displays a registered select filter. The filter bar must contain exactly one select filter with `one` cardinality. The value `all` is reserved for the control that clears the filter. The options `counts`, `tones`, and `labels` are maps keyed by a select option value or `all`. Counts come from the resolver. Labels replace the corresponding option label. Tones describe the meaning of each count. The binding determines whether a change refreshes the view or one zone. Read the selected value with `ctx.parse(scope)`. Apply it to the query yourself.
