What is the use of apex:detail component in Salesforce?

Hello Avnish,

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.

Thanks.

Hi,

To understand it more here is the example -

<!-- For this example to render properly, you must associate the Visualforce page
with a valid account record in the URL.
For example, if 001D000000IRt53 is the account ID, the resulting URL should be:
https://Salesforce_instance/apex/myPage?id=001D000000IRt53
See the Visualforce Developer's Guide Quick Start Tutorial for more information. -->

<apex:page standardController="Account">
<apex:detail subject="{!account.ownerId}" relatedList="false" title="false"/>
</apex:page>

Hope this helps.
