dependent select
how can i make a select that will be disabled by default and filled with data from a custom resource only when another select changes
useSelect hook. This hook allows you to manage select components when records in a resource need to be used as select options. useSelect hook is used to fetch data from the "categories" resource and populate the select options. The defaultValue prop is used to set a default selected option.false to disable the second select. When the first select changes, you can update this state to true to enable the second select and fetch data from the resource.useQuery hook from Refine. The useQuery hook allows you to fetch data from your resources.useQuery hook is used to fetch data from the "firstResource" and "secondResource". The second select is disabled by default and only enabled when a value is selected in the first select. The prop is used to control whether the useQuery hook should fetch data for the second select. When the first select changes, the function is called to update the state and enable the second select.``
In this example, the prop is used to control whether the hook should fetch data. When the first select changes, the function is called to update the SelectqueryOptions.enabledhandleFirstSelectChangeselectedValueimport { useSelect } from "@refinedev/core";
