if you set value to that, you cannot change the valuie any longer@Toskan - yes, this is one of the principles of ReactJS and one-way data binding, and affects all form elements not just this library. This one is simple, no external dependencies, and works with functional and class based components even if it feels a bit hacky.Add a comment if you downvote to improve this answer at least in your opinion As of React v16.8, function-based components have a lot more capability which includes the ability to manage state. I have an issue using react-select.

One of the least fun, yet most important parts of development is configuration. Completelty unrelated from a Login, Signup mechanism but I changed it to be related to your use case.An easy way to solve this is with a parent component in my opinion.If you need to run some functions after state is clearedIf you want multiple input to define in object instead of declaring seperately.Thanks for contributing an answer to Stack Overflow!

Prettier 4. Consider setting the default value in the reducer. In this guide, you will be exposed to different ways of setting default props for different flavors of React components: Using the React.createClass() API; Class components; Functional components; Using higher-order components; React.createClass() Or you just want to have cleaner syntax within your component? Make sure your options have a value attribute.Then match the selects element value initially to the options value.Extending on @isaac-pak's answer, if you want to pass the default value to your component in a prop, you can save it in state in the componentDidMount() lifecycle method to ensure the default is selected the first time.Note, I've updated the following code to make it more complete and to use an empty string as the initial value per the comment.I just went through this myself and chose to set the default value at the reducer INIT function. In this post we are going to go through how we can use the Reacts useState function to manage state within a strongly-typed functional component with TypeScript. In this post, we refactor an existing React TextAreaField component, to make it easier to consume. Where developers & technologists share private knowledge with coworkersProgramming & related technical career opportunitiesthis is correct: value={props.input.value}.

Try updating your code based on my edited response and post back what you find. VS Code extensions and settings.

The point in binding with redux/react is so the ui reflects the value of the object in real time. The Overflow Blog If you said Whether you're coming in fresh to using Typescript with React or are a grizzled veteran looking to add more functional components to your codebase by introducing hooks, it's important to know the different ways to define props.One of the ways you can define props is simply by defining them in the parameter list of a function as demonstrated above.In most cases, the simple way is fine. If you want a quick n' dirty method you could try just changing the component's key which will cause React to unmount your old component instance and mount a fresh one.

Any ideas?I used the defaultValue parameter, below is the code how I achieved a default value as well as update the default value when an option is selected from the drop-down.If you've come here for react-select v2, and still having trouble - version 2 now only accepts an object as I was having a similar error.

Taking the time to think and implement sensible defaults improves the consumption experience of our components.If you enjoyed this post, you might find my course usefulSubscribe to my newsletter to receive notifications on new posts and courses How to set it to have a default value?The point in binding with redux/react is so the ui reflects the value of the object in real time. Where developers & technologists share private knowledge with coworkersProgramming & related technical career opportunitiesHi, thank you for the answer, I was wondering what do you mean by "rekeying"? We could do this using the Alternatively, we can just add the defaults where we destructure the props which is arguably a little more readable:Our consuming component is now as follows, if we are happy to take the default Let’s make our component even nicer by not requiring the So, let’s make this optional in our props interface:We can then only render the label when it contains a value:Job done!
