Picker

It displays a list of values and lets users choose one or multiple items, with optional “Select all” and quick-filtering support. Rendering of both the selected summary and the selectable rows is customizable via callbacks. The picker can bind to external selection state or manage its own, and it can be presented in a dialog with configurable options.

Constructors

Picker

Picker takes the given slice and state to represent the selection. Internally, it uses deep equals, to determine the unique set of selected elements and coordinate that with the UI state.

package main

import (
	"go.wdy.de/nago/presentation/core"
	"go.wdy.de/nago/presentation/ui/picker"
)

func main() {
	type Person struct {
		Name string
		Age  int
	}

	persons := []Person{
		{
			Name: "John",
			Age:  20,
		},
		{
			Name: "Jane",
			Age:  30,
		},
	}

	selected := core.AutoState[[]Person](nil)
	picker.Picker[Person]("Ich bin ein picker", persons, selected)
}
