Feature Request: props.defaultValue as string element

This is feature request

Are you making a feature request?

Provide as much information as possible about your requested feature. Here are a few questions you may consider answering:

Note:

typeof this.state.edata.relates === 'string' //true

• What's your use case? (Tell us about your application and what problem you're trying to solve.)
  • This plugin is very helpful but it has very hard implementation of default value in grouped select ( something like this is needed:

  <Select defaultValue={_.find(_.flatten(_.map(this.state.data,(el)=>el.options)),{value:this.state.edata.relates})} ... />

• What interface do you have in mind? (What new properties or methods do you think might be helpful?)
  • Using it like this for grouped select would be much easier

  <Select defaultValue={this.state.edata.relates} ... />

• Can you point to similar functionality with any existing libraries or components? (Working demos can be helpful.)
  (I dunno.) Maybe, something like on MDB premium:

Greetings @mkikets99,

value and defaultValue were both originally implemented in v1 as string types with support for simpleValues, but this was later removed in v2.

I believe your ask here is different in that you wish react-select to traverse the options and automatically select the option with the matching value. This introduces a lot of complexity with the underlying Types as the primary intention of a defaultValue is to share the same value Type as an Option and not to exist as a parameter to some predicate function.

There has been some talk about how confusing "value" is. While major versions 3, 4, and soon to be 5 have not introduced a lot of breaking changes, version 6 will likely be much different. One of the discussions is to replace what is now known as value with selected. I think this would behave much closer to a native select element where value is understood to represent the value of a selected option.

However for time being, value and defaultValue are meant to be an option object. Since this was addressed as an issue I will transfer this to the Discussions area with other feature requests to have more transparency and support for the long term future direction of react-select.
