What is the form element in HTML5?

The HTML <form> element represents a document section that contains interactive controls for submitting information to a web server.

An HTML form is a section of a document containing normal content, markup, special elements called controls (checkboxes, radio buttons, menus, etc.), and labels on those controls.

Users generally “complete” a form by modifying its controls (entering text selecting menu items, etc.), before submitting the form to an agent for processing.

How to use multiple options in HTML?

The select element creates a menu. Each choice offered by the menu is represented by an option element. A select element must contain at least one option element.

The optgroup element allows authors to group choices logically. This is particularly helpful when the user must choose from a long list of options; groups of related choices are easier to grasp and remember than a single long list of options. In HTML 4.0, all optgroup elements must be specified directly within a select element (i.e., groups may not be nested).

What is a form label in HTML5?

The <label> tag defines a label for a <button>, <input>, <meter>, <output>, <progress>, <select>, or <textarea> element.

The <label> element does not render as anything special for the user. However, it provides a usability improvement for mouse users, because if the user clicks on the text within the <label> element, it toggles the control.

The for attribute of the <label> tag should be equal to the id attribute of the related element to bind them together.
