shadcn vue checkbox indeterminate 复选框中间状态
Radix UI Checkbox’s checked field has a state called “indeterminate”. But It has no effect.
So we need to add the icon while the state is indeterminate.
import icon
import { Check, Minus } from 'lucide-vue-next'
use icon
<CheckboxIndicator class="group/indicator h-full w-full flex items-center justify-center text-current">
<Check class="h-4 w-4 group-[[data-state=indeterminate]]/indicator:hidden" />
<Minus class="text-primary h-4 w-4 group-[[data-state=checked]]/indicator:hidden" />
</CheckboxIndicator>
```
## final code
```vue
<script setup lang="ts">
import type { CheckboxRootEmits, CheckboxRootProps } from 'radix-vue'
import { CheckboxIndicator, CheckboxRoot, useForwardPropsEmits } from 'radix-vue'
import { Check, Minus } from 'lucide-vue-next'
import { cn } from '~/lib/utils'
const props = defineProps<CheckboxRootProps>()
const emits = defineEmits<CheckboxRootEmits>()
const forwarded = useForwardPropsEmits(props, emits)
</script>
<template>
<CheckboxRoot
v-bind="forwarded"
:class="
cn('peer h-4 w-4 shrink-0 rounded-sm border border-primary ring-offset-background focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:cursor-not-allowed disabled:opacity-50 data-[state=checked]:bg-primary data-[state=checked]:text-primary-foreground',
$attrs.class ?? '')"
>
<CheckboxIndicator class="group/indicator h-full w-full flex items-center justify-center text-current">
<Check class="h-4 w-4 group-[[data-state=indeterminate]]/indicator:hidden" />
<Minus class="text-primary h-4 w-4 group-[[data-state=checked]]/indicator:hidden" />
</CheckboxIndicator>
</CheckboxRoot>
</template>
<CheckboxIndicator class="group/indicator h-full w-full flex items-center justify-center text-current">

</CheckboxIndicator>
```
