useSelect - Populate Input Based on Dropdown Selection
Hi!
I have the dropdown --
the resource
products
also returns an associated UnitPrice
value.
I also have an <Input/> for UnitPrice
.
How could I make it so that, when the user selects a product, the <Input/> is repopulated to the new UnitPrice
of the product?14 Replies
Hi @avangeous. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Hmm, I don't know enough to give you a confident answer yet. However, you might find the useSelect hook documentation (https://refine.dev/docs/api-reference/antd/hooks/field/useSelect/) helpful. It provides detailed information on how to use the
useSelect
hook with CRUD components and useForm
.

@kapa.ai How can I populate a separate input based on a dropdown?
Let me check the knowledge base for you. One moment! :books:
----------------------
To populate a separate input based on a dropdown selection, you would need to use a state management solution to store the selected value from the dropdown and then use that value to populate the input field.
In the context of React and Refine, you can use the
useState
hook to store the selected value from the dropdown. When a user selects a product from the dropdown, you can set the state to the UnitPrice
of the selected product. Then, you can use this state value to populate the UnitPrice
input field.
Here's a basic example of how you might do this:
In this example, the onChange
prop of useSelect
is used to update the unitPrice
state whenever a new product is selected. The unitPrice
state is then used as the value for the UnitPrice
input field.
Please note that this is a simplified example and the actual implementation might vary based on your specific use case and the structure of your data.
For more information on how to use the useSelect
hook, you can refer to the Refine useSelect documentation (https://refine.dev/docs/api-reference/antd/hooks/field/useSelect/).

@kapa.ai It's telling me onChange does not exist in useSelect.
Let me check the knowledge base for you. One moment! :books:
----------------------
I apologize for the confusion. You're correct, the
useSelect
hook in Refine does not have an onChange
prop.
The useSelect
hook returns selectProps
which can be spread into a Select component. The Select component from Ant Design does have an onChange
prop that you can use to set the state of the UnitPrice
.
Here's how you can do it:
In this example, the onChange
prop is added directly to the Select component, not the useSelect
hook. When a product is selected, the handleProductChange
function is called, which sets the unitPrice
state to the UnitPrice
of the selected product. The unitPrice
state is then used as the value for the UnitPrice
input field.
Please note that this is a simplified example and the actual implementation might vary based on your specific use case and the structure of your data.
For more information on how to use the useSelect
hook, you can refer to the Refine useSelect documentation (https://refine.dev/docs/api-reference/antd/hooks/field/useSelect/).

@kapa.ai The
options
object only contains the label (Name of the product) & the value (ID of the product) -- is there any way I can add an additional property for UnitPrice?Let me check the knowledge base for you. One moment! :books:
----------------------
Yes, you can add additional properties to the options object in the
useSelect
hook by using the mapDataToOption
prop. This prop allows you to customize the structure of the options object.
Here's an example of how you can add the UnitPrice
to the options object:
In this example, the mapDataToOption
prop is used to customize the structure of the options object. The function receives the original data object as a parameter and returns a new object with the label
, value
, and unitPrice
properties.
Please note that this is a simplified example and the actual implementation might vary based on your specific use case and the structure of your data.
For more information on how to use the useSelect
hook, you can refer to the Refine useSelect documentation (https://refine.dev/docs/api-reference/core/hooks/useSelect/).

@kapa.ai 'mapDataToOption' does not exist in type 'UseSelectProps'.
Let me check the knowledge base for you. One moment! :books:
----------------------
I apologize for the confusion. You're correct, the
useSelect
hook in Refine does not have a mapDataToOption
prop.
The useSelect
hook in Refine does not provide a direct way to add additional properties to the options object. It is designed to work with the optionLabel
and optionValue
props to create the options for the select component.
However, you can achieve your goal by using the useQuery
hook to fetch the data and then manually create the options for the select component. Here's an example:
In this example, the useQuery
hook is used to fetch the data from the products
resource. The data is then mapped to create the options for the Select component, including the unitPrice
property. The onChange
prop of the Select component is used to update the unitPrice
state whenever a new product is selected. The unitPrice
state is then used as the value for the UnitPrice
input field.
Please note that this is a simplified example and the actual implementation might vary based on your specific use case and the structure of your data.
For more information on how to use the useQuery
hook, you can refer to the Refine useQuery documentation (https://refine.dev/docs/api-reference/core/hooks/data/useQuery/).
