Help Extender is developed to address the issues in integrating help to web applications especially with complex forms that requires inline help tool to aid users. Traditionally, we launch a separate window to display help content that is often mislooked because other browser overlaps on it or in some cases loaded to another openned browser. With the Help Extender, integrating help to your web application will be as easy as writing html tag attribute.

We also provided different help sources to centralize help content, make content reusable, and ease of use.

This is a free downloadable script that can be extended under the MIT and GPL open source licenses. It comes “as is” with the following features:

Supports plain text and HTML content from external data source such as a URL.
Pinnable. Allows users to pin the tooltip on user’s screen, thus disabling the auto-hide functionality. This is good for large content or checklist that user needs to read while on the the form.
Draggable. Allow users to drag-drop the tooltip. This is enabled when the tooltip is pinned.
Resizable. Allow users to resize the tooltip according to his/her desired preference. This is enabled when tooltip is pinned.
Scrollable. Content automatically scrolls when it exceeds the size of the tooltip display.
Enables user to explicitly close the tooltip through a close button.
Enables user to show or hide tooltip title bar.
Allows the user to dock the tooltip either left or right.
