Hi @chachi. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base.

----------------------
The

useSelect

useSelect

hook in Refine is designed to fetch data from a single resource and use it as options for a select input. However, if you want to fetch data from multiple resources, you can use multiple instances of

useSelect

useSelect

hook, each for a different resource.

Here is an example of how you can use multiple

useSelect

useSelect

hooks:

import { useSelect } from "@refinedev/core";  

const Component: React.FC = () => {  
  const { options: categories } = useSelect({  
    resource: "categories",  
  });  

  const { options: products } = useSelect({  
    resource: "products",  
  });  

  // Now you have categories and products fetched from their respective resources
  // You can use them in your select inputs or any other components
};

import { useSelect } from "@refinedev/core";  

const Component: React.FC = () => {  
  const { options: categories } = useSelect({  
    resource: "categories",  
  });  

  const { options: products } = useSelect({  
    resource: "products",  
  });  

  // Now you have categories and products fetched from their respective resources
  // You can use them in your select inputs or any other components
};

import { useSelect } from "@refinedev/core";  

const Component: React.FC = () => {  
  const { options: categories } = useSelect({  
    resource: "categories",  
  });  

  const { options: products } = useSelect({  
    resource: "products",  
  });  

  // Now you have categories and products fetched from their respective resources
  // You can use them in your select inputs or any other components
};

import { useSelect } from "@refinedev/core";  

const Component: React.FC = () => {  
  const { options: categories } = useSelect({  
    resource: "categories",  
  });  

  const { options: products } = useSelect({  
    resource: "products",  
  });  

  // Now you have categories and products fetched from their respective resources
  // You can use them in your select inputs or any other components
};

Remember that each instance of

useSelect

useSelect

will trigger a separate query to fetch data from the specified resource. If you want to optimize this behavior, you can use the

staleTime

staleTime

staleTime

staleTime option in the

queryOptions

queryOptions

to avoid refetching data when the component re-renders or when a new instance of the component is created. Here is an example:

const { selectProps } = useSelect({
    resource: "resource",
    defaultValue: props.value,
    optionValue: "id",
    optionLabel: "title",
    queryOptions: {
      staleTime: 1000
    }
});

const { selectProps } = useSelect({
    resource: "resource",
    defaultValue: props.value,
    optionValue: "id",
    optionLabel: "title",
    queryOptions: {
      staleTime: 1000
    }
});

const { selectProps } = useSelect({
    resource: "resource",
    defaultValue: props.value,
    optionValue: "id",
    optionLabel: "title",
    queryOptions: {
      staleTime: 1000
    }
});

const { selectProps } = useSelect({
    resource: "resource",
    defaultValue: props.value,
    optionValue: "id",
    optionLabel: "title",
    queryOptions: {
      staleTime: 1000
    }
});

This will make the query results stay fresh for 1000 milliseconds, and during this time, any new instances of the component will reuse the existing data instead of triggering a new query (source (https://github.com/refinedev/refine/issues/1815)).

For more information on how to use the

useSelect

useSelect

hook, you can refer to the documentation:

@kapa.ai Can I use useSelect not on resource but on __type (Enum) in GraphQL?

Let me check the knowledge base for you. One moment!

----------------------
The

useSelect

useSelect

hook in Refine is designed to fetch data from a resource and use it as options for a select input. It's not directly designed to work with GraphQL

__type

__type

__type

__type (Enum), as it expects a resource name to fetch the data.

However, you can create a custom hook that uses the

useQuery

useQuery

hook to fetch the enum values from your GraphQL API and format them in a way that can be used as options for a select input.

Here is an example of how you can create such a hook:

import { useQuery } from "@refinedev/core";

const useEnum = (enumName: string) => {
  const { data } = useQuery({
    query: `
      query {
        __type(name: "${enumName}") {
          enumValues {
            name
          }
        }
      }
    `,
  });

  const options = data?.__type?.enumValues?.map((value: any) => ({
    label: value.name,
    value: value.name,
  }));

  return { options };
};

import { useQuery } from "@refinedev/core";

const useEnum = (enumName: string) => {
  const { data } = useQuery({
    query: `
      query {
        __type(name: "${enumName}") {
          enumValues {
            name
          }
        }
      }
    `,
  });

  const options = data?.__type?.enumValues?.map((value: any) => ({
    label: value.name,
    value: value.name,
  }));

  return { options };
};

import { useQuery } from "@refinedev/core";

const useEnum = (enumName: string) => {
  const { data } = useQuery({
    query: `
      query {
        __type(name: "${enumName}") {
          enumValues {
            name
          }
        }
      }
    `,
  });

  const options = data?.__type?.enumValues?.map((value: any) => ({
    label: value.name,
    value: value.name,
  }));

  return { options };
};

import { useQuery } from "@refinedev/core";

const useEnum = (enumName: string) => {
  const { data } = useQuery({
    query: `
      query {
        __type(name: "${enumName}") {
          enumValues {
            name
          }
        }
      }
    `,
  });

  const options = data?.__type?.enumValues?.map((value: any) => ({
    label: value.name,
    value: value.name,
  }));

  return { options };
};

You can then use this hook in your component like this:

const Component: React.FC = () => {
  const { options } = useEnum("YourEnumName");

  // Now you can use the options in your select input
};

const Component: React.FC = () => {
  const { options } = useEnum("YourEnumName");

  // Now you can use the options in your select input
};

const Component: React.FC = () => {
  const { options } = useEnum("YourEnumName");

  // Now you can use the options in your select input
};

const Component: React.FC = () => {
  const { options } = useEnum("YourEnumName");

  // Now you can use the options in your select input
};

Please replace

"YourEnumName"

"YourEnumName"

"YourEnumName"

"YourEnumName" with the actual name of your enum.

Remember that this is a custom solution and might need adjustments based on your GraphQL API and your requirements. For more information on how to use the

useQuery

useQuery

hook, you can refer to the useQuery documentation (https://refine.dev/docs/data/hooks/use-query).
