A custom Visualforce component. All custom component definitions must be wrapped inside a
single <apex:component> tag.

An HTML input element of type text. Use this component to get user input for a controller method
that does not correspond to a field on a Salesforce object.
This component does not use Salesforce styling. Also, since it does not correspond to a field, or
any other data on an object, custom code is required to use the value the user inputs.

A Visualforce chart. Defines general characteristics of the chart, including size and data binding.

A single piece of data in an <apex:pageBlockSection> that takes up one column in one row. An
<apex:pageBlockSectionItem> component can include up to two child components. If no content is
specified, the column is rendered as an empty space. If one child component is specified, the
content spans both cells of the column. If two child components are specified, the content of the

first is rendered in the left, “label” cell of the column, while the content of the second is rendered in
the right, “data” cell of the column.
Note that if you include an <apex:outputField> or an <apex:inputField> component in an
<apex:pageBlockSectionItem>, these components do not display with their label or custom help
text as they do when they are children of an <apex:pageBlockSectionItem>. Also note that
<apex:pageBlockSectionItem> components cannot be rerendered; rerender the child components
instead.

A component that creates an inline frame within a Visualforce page. A frame allows you to keep
some information visible while other information is scrolled or replaced.

The standard detail page for a particular object, as defined by the associated page layout for the
object in Setup. This component includes attributes for including or excluding the associated
related lists, related list hover links, and title bar that appear in the standard Salesforce application
interface.
