useAutocomplete

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

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

You can pass the pageSize to the pagination property.

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

It can be "off", "client" or "server". It is used to determine whether to use server-side pagination or not.

useAutocomplete({
  pagination: {
    mode: "off",
  },
});

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.

useAutocomplete({
  resource: "categories",
  defaultValueQueryOptions: {
    onSuccess: (data) => {
      console.log("triggers when on query return on success");
    },
  },
});

It allows us to AutoComplete the options.

For more information, refer to the CrudFilters interface documentation →

import { useAutocomplete } from "@refinedev/mui";
import { Autocomplete, TextField } from "@mui/material";

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

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

  return (
    <Autocomplete
      {...autocompleteProps}
      getOptionLabel={(item) => item.title}
      isOptionEqualToValue={(option, value) =>
        value === undefined ||
        option?.id?.toString() === (value?.id ?? value)?.toString()
      }
      placeholder="Select a category"
      renderInput={(params) => (
        <TextField
          {...params}
          label="Category"
          margin="normal"
          variant="outlined"
          required
        />
      )}
    />
  );
};

If onSearch is used, it will override the existing filters.

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.

import { createFilterOptions } from "@mui/material";

const { autocompleteProps } = useAutocomplete({
  resource: "categories",
});

const filterOptions = createFilterOptions({
  matchFrom: "start",
  stringify: (option: any) => option.title,
});

<Autocomplete
  {...autocompleteProps}
  getOptionLabel={(item) => item.title}
  onInputChange={(event, value) => {}}
  filterOptions={filterOptions}
  isOptionEqualToValue={(option, value) =>
    value === undefined ||
    option?.id?.toString() === (value?.id ?? value)?.toString()
  }
  placeholder="Select a category"
  renderInput={(params) => (
    <TextField
      {...params}
      label="Category"
      margin="normal"
      variant="outlined"
      required
    />
  )}
/>;

meta is a special property that can be used to pass additional information to data provider methods for the following purposes:

• Customizing the data provider methods for specific use cases.
• Generating GraphQL queries using plain JavaScript Objects (JSON).

For more information, refer to the meta section of the General Concepts documentation →

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

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

const myDataProvider = {
  //...
  getList: async ({
    resource,
    pagination,
    sorters,
    filters,
    meta,
  }) => {
    const headers = meta?.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.

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

NotificationProvider is required for this prop to work.

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

useAutocomplete({
  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, useAutocomplete will call open function from NotificationProvider to show a error notification. With this prop, you can customize the error notification.

useAutocomplete({
  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, please refer to the Live / Realtime documentation

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

LiveProvider is required for this prop to work.

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

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

LiveProvider is required for this prop to work.

Params to pass to liveProvider's subscribe method.

If you want loading overtime for the request, you can pass the overtimeOptions prop to the this hook. It is useful when you want to show a loading indicator when the request takes too long. interval is the time interval in milliseconds while onInterval is the function that will be called on each interval.

Return overtime object from this hook. elapsedTime is the elapsed time in milliseconds. It becomes undefined when the request is completed.

const { overtime } = useAutocomplete({
  //...
  overtimeOptions: {
    interval: 1000,
    onInterval(elapsedInterval) {
      console.log(elapsedInterval);
    },
  },
});

console.log(overtime.elapsedTime); // undefined, 1000, 2000, 3000 4000, ...

// You can use it like this:
{
  elapsedTime >= 4000 && <div>this takes a bit longer than expected</div>;
}

Use sorters instead.

Use pagination.mode instead.

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 selected.

import { useAutocomplete } from "@refinedev/mui";
import { Autocomplete, TextField } from "@mui/material";

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

const PostCreate: React.FC = () => {
  const { autocompleteProps } = useAutocomplete<ICategory>({
    resource: "categories",
    defaultValue: 11,
  });

  return (
    <Autocomplete
      {...autocompleteProps}
      getOptionLabel={(item) => item.title}
      isOptionEqualToValue={(option, value) =>
        value === undefined ||
        option?.id?.toString() === (value?.id ?? value)?.toString()
      }
      placeholder="Select a category"
      renderInput={(params) => (
        <TextField
          {...params}
          label="Category"
          margin="normal"
          variant="outlined"
          required
        />
      )}
    />
  );
};

You can create a new options object with queryResult.

const { autocompleteProps, queryResult } = useAutocomplete();

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

return <Autocomplete {...autocompleteProps} options={options || []} />;

import { Create, useAutocomplete } from "@refinedev/mui";
import { Box, Autocomplete, TextField } from "@mui/material";
import { useForm } from "@refinedev/react-hook-form";
import { Controller } from "react-hook-form";

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

const PostCreate: React.FC = () => {
  const {
    saveButtonProps,
    refineCore: { formLoading, queryResult },
    register,
    control,
    formState: { errors },
  } = useForm<IPost, HttpError, IPost & { category: ICategory }>();

  const { autocompleteProps } = useAutocomplete<ICategory>({
    resource: "categories",
  });

  return (
    <Create isLoading={formLoading} saveButtonProps={saveButtonProps}>
      <Box component="form">
        <Controller
          control={control}
          name="category"
          rules={{ required: "This field is required" }}
          render={({ field }) => (
            <Autocomplete
              {...autocompleteProps}
              {...field}
              onChange={(_, value) => {
                field.onChange(value);
              }}
              getOptionLabel={({ title }) => title}
              isOptionEqualToValue={(option, value) =>
                value === undefined ||
                option?.id?.toString() === (value?.id ?? value)?.toString()
              }
              placeholder="Select a category"
              renderInput={(params) => (
                <TextField
                  {...params}
                  label="Category"
                  margin="normal"
                  variant="outlined"
                  error={!!errors.category}
                  helperText={errors.category?.message}
                  required
                />
              )}
            />
          )}
        />
      </Box>
    </Create>
  );
};

The use of useAutocomplete with useForm is demonstrated in the code above. You can use the useAutocomplete hook independently of the useForm hook.

By default, Refine does the search using the useList hook and passes it to the search parameter. If you get a problem you should check your getList function in your Data Provider. If you want to change this behavior to make client-side filtering, you can examine this documentation.
