<FormControl sx={{ padding: 0 }}>
<Controller
control={control}
name={fieldName}
rules={{
required: t("errors.required.field", { field: fieldName }),
validate: (value) => {
console.log(value, options);
if (!options.some((option) => option.id === value.id)) {
return t("errors.invalid.option", { field: fieldName });
}

Hi @Joe Gaffney. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
To report an error if the value is not in the options for a Material UI
Autocomplete
component using react-hook-form
, you can use the Controller
component to manage the form state and validation. The validate
function in the rules
prop can be used to check if the selected value exists in the options.
Here's an example based on the knowledge sources provided:
In this example, the validate
function checks if the selected value's id
is present in the options
array. If not, it returns an error message. The renderInput
function of the Autocomplete
component uses a TextField
to display any validation errors.
For more information, you can refer to the refine documentation on using useAutocomplete
with CRUD
components and useForm
(https://refine.dev/docs/ui-integrations/material-ui/hooks/use-auto-complete/#how-do-i-use-it-with-crud-components-and-useform).

@kapa.ai this is not working is the validate only ran on change issue i am having is my options change based on previous feild choices.
Let me check the knowledge base for you again. One moment! :books:
----------------------
To handle dynamic options in a
react-hook-form
setup with Material UI's Autocomplete
, you need to ensure that the validation logic is triggered whenever the options change. The validate
function in the rules
prop is typically run on change, but you can manually trigger validation when the options change by using the trigger
method from react-hook-form
.
Here's how you can approach this:
1. Use the useEffect
Hook: Monitor changes to the options and trigger validation when they change.
2. Trigger Validation: Use the trigger
method from react-hook-form
to manually validate the field when the options change.
Here's an example implementation:
In this example, the useEffect
hook is used to watch for changes in the options
array. Whenever the options
change, the trigger
function is called to re-validate the "category" field. This ensures that the validation logic is applied even when the options are updated based on previous field choices.
For more details on using react-hook-form
with dynamic data, you can refer to the React Hook Form documentation (https://react-hook-form.com/docs/useform).

@kapa.ai i short of just want to redraw if the options change or rest the value
Let me check the knowledge base for you again. One moment! :books:
----------------------
To reset the value or redraw the
Autocomplete
component when the options change, you can use the useEffect
hook to monitor changes in the options and reset the field value using the setValue
method from react-hook-form
. This approach ensures that the Autocomplete
component updates its state whenever the options change.
Here's how you can implement this:
In this example, the useEffect
hook is used to reset the "category" field to null
whenever the options
array changes. This effectively redraws the Autocomplete
component with the updated options and resets the selected value, ensuring that the component reflects the current state of the options.
For more information on managing form state with react-hook-form
, you can refer to the React Hook Form documentation (https://react-hook-form.com/docs/useform).

@kapa.ai how i can reset a value of the form feild outsidte from a use effect
Let me check the knowledge base for you again. One moment! :books:
----------------------
To reset the value of a form field outside of a
useEffect
hook using react-hook-form
, you can use the reset
or setValue
methods provided by the useForm
hook. These methods can be called in response to any event or condition in your component.
Here's an example of how you can reset a form field value using a button click:
In this example, the handleReset
function is called when the "Reset Category" button is clicked. It uses the setValue
method to reset the "category" field to an empty string. Alternatively, you can use the reset
method to reset the entire form to its default values.
For more details on using react-hook-form
, you can refer to the React Hook Form documentation (https://react-hook-form.com/docs/useform).

@kapa.ai is there not a way with ther controller
Let me check the knowledge base for you again. One moment! :books:
----------------------
Yes, you can reset a form field value using the
Controller
component in react-hook-form
. The Controller
component itself doesn't directly provide a method to reset values, but you can use the setValue
method from the useForm
hook in conjunction with Controller
to achieve this.
Here's how you can do it:
In this example, the handleReset
function is used to reset the "category" field by calling setValue
with an empty string. This approach allows you to reset the field value while using the Controller
component to manage the form field.
For more information on using react-hook-form
with Controller
, you can refer to the React Hook Form documentation (https://react-hook-form.com/docs/useform).
