Hi @Tinkly. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To answer your question about the USelect default value and how to handle it in a Zod schema, let's refer to the relevant information from the Nuxt UI documentation. For the USelect component, you can provide a default value in the v-model as follows: 1. For string options:
<script setup lang="ts">
const countries = ['United States', 'Canada', 'Mexico']
const country = ref(countries[0])
</script>

<template>
<USelect v-model="country" :options="countries" />
</template>
<script setup lang="ts">
const countries = ['United States', 'Canada', 'Mexico']
const country = ref(countries[0])
</script>

<template>
<USelect v-model="country" :options="countries" />
</template>
2. For object options:
<script setup lang="ts">
const countries = [{
name: 'United States',
value: 'US'
}, {
name: 'Canada',
value: 'CA'
}, {
name: 'Mexico',
value: 'MX'
}]

const country = ref('CA')
</script>

<template>
<USelect v-model="country" :options="countries" option-attribute="name" value-attribute="value" />
</template>
<script setup lang="ts">
const countries = [{
name: 'United States',
value: 'US'
}, {
name: 'Canada',
value: 'CA'
}, {
name: 'Mexico',
value: 'MX'
}]

const country = ref('CA')
</script>

<template>
<USelect v-model="country" :options="countries" option-attribute="name" value-attribute="value" />
</template>
Source: Select Component For handling this in a Zod schema, you can use the default() method to set a default value. Here's an example of how you might structure your Zod schema:
const validationSchema = toTypedSchema(
object({
country: z
.string()
.default('US') // Set the default value here
})
)
const validationSchema = toTypedSchema(
object({
country: z
.string()
.default('US') // Set the default value here
})
)
This schema assumes you're using the value of the selected option. If you're using the entire object, you'd need to adjust the schema accordingly. Remember to import the necessary Zod functions and ensure you're using the correct types for your specific use case. If you need more specific guidance on integrating this with form fields or have a more complex schema, please provide more details about your form structure and requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I want it to not have a value by default

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on your request to have no default value for the USelect component, here's how you can achieve that: 1. For the v-model of the USelect component, you can initialize it with null or undefined:
<script setup lang="ts">
const selected = ref(null) // or ref(undefined)
</script>

<template>
<USelect v-model="selected" :options="options" />
</template>
<script setup lang="ts">
const selected = ref(null) // or ref(undefined)
</script>

<template>
<USelect v-model="selected" :options="options" />
</template>
2. To handle this in your Zod schema, you can use the .nullable() or .optional() method, depending on whether you want to allow null or undefined values:
const validationSchema = toTypedSchema(
object({
selectedOption: z.string().nullable() // or z.string().optional()
})
)
const validationSchema = toTypedSchema(
object({
selectedOption: z.string().nullable() // or z.string().optional()
})
)
This setup allows the select to have no value by default, and the schema will accept either a string value or null/undefined. If you're using the USelect within a UForm component, you can set up your state like this:
<script setup lang="ts">
const state = reactive({
selectedOption: null // or undefined
})
</script>
<script setup lang="ts">
const state = reactive({
selectedOption: null // or undefined
})
</script>
This approach ensures that the select doesn't have a pre-selected value when the form is initially rendered. Source: Select Component Remember to adjust the field names and types according to your specific use case. If you need further clarification or have more specific requirements, please let me know. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
