How do we add a single-line input field in HTML?

Use the <isindex> tag to add a single-line input field. The HTML <isindex> tag is used for querying a document through a text field. The tag can be used anywhere but head tag is preferable. Note: It is a deprecated tag and should not be used.

The following are the attributes −

Attribute
 Value
 Description
Prompt
 string
 Label for the text field
Action
 URL
 used when a query needs to be sent to a different URL

Example

Try the following code −

<!Doctype html> <html>    <head>       <title>HTML isindex Tag</title>       <isindex prompt = "Search" />    </head> </html>
