Hi @ganuzaz. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The useSelect hook in refine allows you to manage Ant Design's Select component when the records in a resource need to be used as select options. This hook uses the useList hook for fetching data. Here is a basic example of how to use useSelect hook with Ant Design:

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { selectProps } = useSelect<ICategory>({  
 resource: "categories",  
 });  
  
 return (  
 <Select  
 placeholder="Select a category"  
 style={{ width: 300 }}  
 {...selectProps}  
 />  
 );  
};

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { selectProps } = useSelect<ICategory>({  
 resource: "categories",  
 });  
  
 return (  
 <Select  
 placeholder="Select a category"  
 style={{ width: 300 }}  
 {...selectProps}  
 />  
 );  
};

In this example, useSelect is used to fetch data from the "categories" resource. The fetched data is used to populate the options of the Select component. The selectProps returned by useSelect are spread into the Select component to provide it with the necessary props. For more detailed information, you can refer to the refine useSelect documentation (https://refine.dev/docs/api-reference/antd/hooks/field/useSelect/). Please note that the useSelect hook includes out-of-the-box features such as fetchSize, sorting, and filtering. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai How do i set the initial value on useSelect?

kapa.ai•16mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- You can set the initial value of the useSelect hook by using the defaultValue property. This property can be used to set default options for a Select component and also add extra options. Here is an example of how to use it:

const { selectProps } = useSelect<ICategory>({  
 resource: "categories",  
 defaultValue: 11,  
});

const { selectProps } = useSelect<ICategory>({  
 resource: "categories",  
 defaultValue: 11,  
});

In this example, the defaultValue is set to 11. This means that when the Select component is first rendered, the option with the value of 11 will be selected by default. Please note that the defaultValue can be a single value or an array of values. For example:

useSelect({  
 defaultValue: 1, // or [1, 2]  
});

useSelect({  
 defaultValue: 1, // or [1, 2]  
});

For more detailed information, you can refer to the refine useSelect documentation (https://refine.dev/docs/api-reference/antd/hooks/field/useSelect/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai the defaultValue doesn't have the proper label for it

kapa.ai•16mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In some cases, you might only have the id of the default value and it may be necessary to show the proper label for it in the selection box. To handle this, refine sends a request via the useMany hook, gets the data, and marks it as selected. Here's an example of how to use it:

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const ProductCreate: React.FC = () => {  
 const { selectProps } = useSelect<ICategory>({  
 resource: "categories",  
 defaultValue: 11,  
 });  
  
 return (  
 <Select  
 placeholder="Select a category"  
 style={{ width: 300 }}  
 {...selectProps}  
 />  
 );  
};

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const ProductCreate: React.FC = () => {  
 const { selectProps } = useSelect<ICategory>({  
 resource: "categories",  
 defaultValue: 11,  
 });  
  
 return (  
 <Select  
 placeholder="Select a category"  
 style={{ width: 300 }}  
 {...selectProps}  
 />  
 );  
};

In this example, the defaultValue is set to 11. The useSelect hook sends a useMany query to the backend with the defaultValue and appends it to the options of the Select component, ensuring the default values exist in the current options array. For more detailed information, you can refer to the refine useSelect documentation (https://refine.dev/docs/api-reference/antd/hooks/field/useSelect/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai im using the infinite select antd on github and the defaultValue doesn't appropriately shows its label

kapa.ai•16mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In refine, when using the useSelect hook with Ant Design's Select component, you can set a default value using the defaultValue property. However, if you only have the id of the default value and need to display the corresponding label, refine handles this by sending a request via the useMany hook to fetch the data and mark it as selected. Here's an example of how to use it:

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { selectProps } = useSelect<ICategory>({  
 resource: "categories",  
 defaultValue: 11,  
 });  
  
 return (  
 <Select  
 placeholder="Select a category"  
 style={{ width: 300 }}  
 {...selectProps}  
 />  
 );  
};

import { useSelect } from "@refinedev/antd";  
import { Select } from "antd";  
  
interface ICategory {  
 id: number;  
 title: string;  
}  
  
const PostCreate: React.FC = () => {  
 const { selectProps } = useSelect<ICategory>({  
 resource: "categories",  
 defaultValue: 11,  
 });  
  
 return (  
 <Select  
 placeholder="Select a category"  
 style={{ width: 300 }}  
 {...selectProps}  
 />  
 );  
};

Hey, @ganuzaz You can try adding a label key to the defaultValue prop of the Select component as follows.

<Select                  defaultValue={{
    label: "Foo",
    value: "foo",
  }}
  ...

<Select                  defaultValue={{
    label: "Foo",
    value: "foo",
  }}
  ...

sorry, i just tested this, its showing the label but the Form component above it doesn't have the value of it putting the value into the Form component's initialValues will instead show the value again instead of the label nvm i added form.setFieldValue on useEffect and it works, thanks!
