title: How can I implement FormValidation in React?
body: <p>I created a FormValidation Function for my React-App Project. I use the tutorial <a href="https://medium.com/code-monkey/client-side-form-validation-in-react-40e367de47ba" rel="nofollow noreferrer">"Form Validation in React"</a> to implement this. You can find a demonstration Project on <a href="https://github.com/mikeries/react-validation-tutorial" rel="nofollow noreferrer">Github</a>. The Problem is, that this FormValidation doesn't work in my Project. I don't know why.</p>

  <p>I am aware that it takes time to help me, but I would be very grateful for it because I have little knowledge about that. Because the files are too large to insert here, I created SandBox.io project. This is exactly the same project that I use myself:</p>

  <p>Thanks for our help. For my React-App, I am using the Evergreen UI Framework. You can find the Props for the TextInputFields (Which I use) <a href="http://evergreen-v4.surge.sh/components/text-input" rel="nofollow noreferrer">here</a>.</p>
