How to force selection in React Select?-CodePudding

I have a select list (from react-select library). How to force the first item of the seasons array to be selected by default and how to carry out the renderMatches function depending on that automatic choice? My not-working solution:

<Select
  onChange = {(e) => renderMatches(e)}
  value = {seasons[0]}
  options = {seasons}
/>

CodePudding user response：

is <Select /> a component that you have created?

if Yes I will need some more info to answer your question, if No are you using a library? which one?

On the other hand, you should probably have a selected state or something that goes into value={selected} and you can set the default value of it in the componentDidMount or in useEffect hook.

You can try the defaultValue prop for the react-select component, that fixes the default value on render. Here is an example of that:

After that, the value will be set to whatever you set the value prop to. I might be missing something else, but from the code I can't really tell what you are trying to accomplish with the renderMatches function.

CodePudding user response：

You can do so by converting the first value of array as

let seasonValue = {
  value: seasons[0].YourValue,
  label: seasons[0].YourLabel,
};
this.setState({ value: seasonValue });

and you can use can use this value

<Select
onChange = {(e) => renderMatches(e)}
value = {value}
options = {seasons} 
/>
