useSelect

pagination will be passed to the getList method from the dataProvider as parameter. It is used to send pagination query parameters to the API.

You can pass the current page number to the pagination property.

useSelect({
  pagination: {
    current: 2,
  },
});

You can pass the pageSize to the pagination property.

useSelect({
  pagination: {
    pageSize: 20,
  },
});

hasPagination will be passed to the getList method from the dataProvider as parameter via the useList hook. It is used to determine whether to use server-side pagination or not.

useSelect({
  hasPagination: false,
});

When the defaultValue property is given, the useMany data hook is called for the selected records. With this property, you can change the options of this query. If not given, the values given in queryOptions will be used.

const { options } = useSelect({
  defaultValueQueryOptions: {
    onSuccess: (data) => {
      console.log("triggers when on query return on success");
    },
  },
});

It allows us to AutoComplete the options.

Refer to the CrudFilters interface for more information →

import { Select, useSelect } from "@pankod/refine-mantine";

interface ICategory {
    id: number;
    title: string;
}

const ProductCreate: React.FC = () => {
    const { selectProps } = useSelect<ICategory>({
        resource: "categories",
        onSearch: (value) => [
            {
                field: "title",
                operator: "contains",
                value,
            }
        ]
    });

    return (
        <Select
            label="Category"
            placeholder="Select a category"
            withinPortal
            {...selectProps}
        />
    );
};

Sometimes, you may want to filter the options on the client-side. You can do this by passing onSearch function as undefined. This will disable the server-side filtering and will filter the options on the client-side. Set the searchValue and onSearchChange properties to enable the search input.

const { selectProps } = useSelect({
  resource: "categories",
});

const [searchValue, onSearchChange] = useState("");

<Select
  {...selectProps}
  onSearch={undefined}
  onSearchChange={onSearchChange}
  searchValue={searchValue}
/>;

metaData is used following two purposes:

• To pass additional information to data provider methods.
• Generate GraphQL queries using plain JavaScript Objects (JSON). Please refer GraphQL for more information.

In the following example, we pass the headers property in the metaData object to the create method. With similar logic, you can pass any properties to specifically handle the data provider methods.

useSelect({
  metaData: {
    headers: { "x-meta-data": "true" },
  },
});

const myDataProvider = {
  //...
  getList: async ({
    resource,
    pagination,
    hasPagination,
    sort,
    filters,
    metaData,
  }) => {
    const headers = metaData?.headers ?? {};
    const url = `${apiUrl}/${resource}`;
    //...
    //...
    const { data, headers } = await httpClient.get(`${url}`, { headers });
    return {
      data,
    };
  },
  //...
};

If there is more than one dataProvider, you can specify which one to use by passing the dataProviderName prop. It is useful when you have a different data provider for different resources.

useSelect({
  dataProviderName: "second-data-provider",
});

NotificationProvider is required for this prop to work.

After data is fetched successfully, useSelect can call open function from NotificationProvider to show a success notification. With this prop, you can customize the success notification.

useSelect({
  successNotification: (data, values, resource) => {
    return {
      message: `${data.title} Successfully fetched.`,
      description: "Success with no errors",
      type: "success",
    };
  },
});

NotificationProvider is required for this prop to work.

After data fetching is failed, useSelect will call open function from NotificationProvider to show a error notification. With this prop, you can customize the error notification.

useSelect({
  errorNotification: (data, values, resource) => {
    return {
      message: `Something went wrong when getting ${data.id}`,
      description: "Error",
      type: "error",
    };
  },
});

LiveProvider is required for this prop to work.

Determines whether to update data automatically ("auto") or not ("manual") if a related live event is received. It can be used to update and show data in Realtime throughout your app. For more information about live mode, please check Live / Realtime page.

useSelect({
  liveMode: "auto",
});

LiveProvider is required for this prop to work.

The callback function that is executed when new events from a subscription are arrived.

useSelect({
  onLiveEvent: (event) => {
    console.log(event);
  },
});

LiveProvider is required for this prop to work.

Params to pass to liveProvider's subscribe method.

onSearch is a function that is used to set the search value. It is useful when you want to search for a specific value. A simple example of this is shown below.

import { Select, useSelect } from "@pankod/refine-mantine";

interface ICategory {
    id: number;
    title: string;
}

const ProductCreate: React.FC = () => {
    const { selectProps } = useSelect<ICategory>({
        resource: "categories",
        onSearch: (value) => [
            {
                field: "title",
                operator: "contains",
                value,
            }
        ]
    });

    return (
        <Select
            label="Category"
            placeholder="Select a category"
            withinPortal
            {...selectProps}
        />
    );
};

In some cases we only have id, it may be necessary to show it selected in the selection box. This hook sends the request via useMany, gets the data and mark as seleted.

import { Select, useSelect, Button } from "@pankod/refine-mantine";

interface ICategory {
    id: number;
    title: string;
}

const ProductCreate: React.FC = () => {

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

    return (
        <>
            <Select
                label="Category"
                placeholder="Select a category"
                withinPortal
                {...selectProps}
            />
        </>
    );
};

optionLabel and optionValue are used to change the value of your options. The default values are optionsLabel="title" and optionsValue="id".

To change to name and categoryId;

useSelect({
  optionLabel: "name",
  optionValue: "categoryId",
});

Sometimes it may not be enough to create optionLabel and optionValue options. In this case we create options with queryResult.

const { queryResult } = useSelect();

const options = queryResult.data?.data.map((item) => ({
  label: item.title,
  value: item.id,
}));

return <Select options={options} />;
