Set Null as default value in useSelect
Is there a way to always set select value to null by default of no option is selected?

Hi @tads8799. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Yes, you can set the
defaultValue
to null
in the useSelect
hook to have a default null option if no one is selected. Here is how you can do it:
In this code, useSelect
is a hook provided by Refine that allows you to fetch data from a resource and use it as options for a select box. The defaultValue
property is used to set a default option for the select box. By setting it to null
, you're specifying that if no option is selected, the value should be null
.
For more information, you can refer to the useSelect documentation (https://refine.dev/docs/api-reference/core/hooks/useSelect/).

In the document, the type for defaultValue is BaseKey, which is string and number only, not null
@kapa.ai
Let me check the knowledge base for you. One moment! :books:
Sorry @tads8799, I seem to be having a bit of trouble. Don't worry though, I've pinged my supprt and they will try to fix me up! :technologist:
Perhaps try again in 15mins?

Hello @tads8799, I believe this is just a type error and will not effect logic
can you try this please ?
hmm actually maybe it can. sorry. but no harm to try 😄
why you want to set default value to null ? maybe we can think other solutions for this problem besides null

It's just how the backend and database is required, I must follow.😅

is it worked ?, by default useSelect's default value is
[]
maybe you can sent null value if array is empty

I manage to convince the backend deveoper to ommit the null case.
But I'll take note of your answer. Tk you
