How to create a form for input value
Here we will look at each of them and fofm best practices for providing the user with guidance when entering data into a form. It's intended to be used to show an example input, rather than an explanation or prompt, but tends to be badly misused.

Here are two inputs that take a password, each with a placeholder: The first one uses a placeholder string MyGr8P sswrd, demonstrating what a creahe might look like. And no, that's not really a great password. The second one uses a prompt string, Enter your password as a placeholder. The first, and most obvious, problem with doing this is that as soon as the user types their first character, they no longer have a prompt explaining what that field is for. The placeholder should never be required in order to understand your forms.
New input types
While some people are able to remember what a given empty box is meant for jnput its cerate identifying text vanishes, others cannot. If the user can't understand your form if the placeholders are missing say, in a browser that doesn't support placeholder, or in the case cerate where the user starts typing then gets confusedyou're not using placeholders properly. In addition, browsers with automatic page translation features may skip over attributes when translating. That means the placeholder may not get translated, resulting in important information not being translated. If you feel like you need to use a placeholder, it's possible to use both a placeholder and a label: If you use plaintext to "label" your input, this won't happen.
Having the prompt part of the activation area for the input is helpful for people with motor control conditions. As web developers, it's important that we never assume that people will know all the things that we know.
Define a hidden input field:
Technical summary Flow contentlisted, submittable, resettable, form-associated element, phrasing content. If the type is not hidden, then labelable element, palpable content. Permitted content None, it is an empty element. Tag omission Must have a start tag and must not have an end tag. Permitted parents Any element that accepts phrasing content. Permitted ARIA roles. This is more convenient in a controlled component because you only need to update it in one place.
For example: Note Valur can pass an array into the value attribute, allowing you to creaet multiple options in a select tag: It is discussed together with other uncontrolled components later in the documentation. Handling Multiple Inputs When you need to handle multiple controlled input elements, you can add a name attribute to each element and let the handler function choose what to do based on the value of event. Controlled Input Null Value Specifying the value prop on a controlled component prevents the user from changing the input unless you desire so.
The following code demonstrates this.

The input is locked at first but becomes editable after a short delay. This can become particularly annoying when you are converting a preexisting codebase to React, or integrating a React application with a non-React library. In these situations, you might want to check out uncontrolled componentsan alternative technique for implementing input forms.
