RadioGroup

The exclusive choice: labeled circles, exactly one selected.

State lives on the struct (Selected); clicks are processed at the top of Layout. Per-option disabling is index-aligned, like Tabs.

Installation

Use the module import (the default), or own the source: lotusui add vendors the component into your app and lotusui update keeps the copy mergeable — see Registry.

go get github.com/ikaito-com/lotusui

# or vendor the source into your app:
go run github.com/ikaito-com/lotusui/cmd/lotusui add radio-group

Usage

var density = lotusui.RadioGroup{Selected: 0}

Description

Descriptions, index-aligned, render muted under each label.

density := lotusui.RadioGroup{Descriptions: []string{
	"Standard spacing for most use cases.",
