HTML <isindex> Tag

The <isindex> tag is used to display search strings in the current document. The tag is placed inside the <head> element.

The <isindex> tag is deprecated and not supported correctly by the browsers. In order to define a single line input field, you need to use the <input> tag with the <label> tag, which executes the same function as the prompt attribute.

Syntax

The <isindex> tag is an empty element, so the closing tag isn’t required.

In XHTML we must close the tag (</isindex>).

Example

<!DOCTYPE html>
<html>
  <head>
    <isindex prompt = "Search a text" />
  </head>
</html>

Attributes
