The input form attribute specifies the form the input element belongs to.
The value of this attribute must be equal to the id attribute of the form element it belongs to.

Passing Data Through Props
To get our feet wet, let’s try passing some data from our Board component to our Square component.
We strongly recommend typing code by hand as you’re working through the tutorial and not using copy paste. This will help you develop muscle memory and a stronger understanding.
Dropdowns Toggle contextual overlays for displaying lists of links and more with the Bootstrap dropdown plugin.
It also includes support for previous next controls and indicators.
In browsers where the Page Visibility API is supported, the carousel will avoid sliding when the webpage is not visible to the user (such as when the browser tab is inactive, the browser window is minimized, etc.).
Handling Events Handling events with React elements is very similar to handling events on DOM elements. There are some syntax differences:
React events are named using camelCase, rather than lowercase.
With JSX you pass a function as the event handler, rather than a string.
It lets you compose complex UIs from small and isolated pieces of code called “components”. React has a few different kinds of components, but we’ll start with React.Component subclasses:
Components and Props Components let you split the UI into independent, reusable pieces, and think about each piece in isolation.
This page provides an introduction to the idea of components. You can find a detailed component API reference here.
