The Porthole module allows users to display the contents of another web page or site on a tab.


This module functions within the standard role-based security inheritance chain described in the tab designer topic.  Administrative users can configure additional module settings by clicking the  button.


NOTE: This module uses IFRAME elements and some browsers will need special configuration to allow the display of content in IFRAMES - consult your browser documentation to see if this applies to you.


It is recommended that when specifying the source URL for the remote content that you specify the HTTPS protocol rather than HTTP if the remote site supports it.  This ensures a secure viewing experience.


NOTE: Not all sites are compatible with IFRAME elements and if they detect that they are in an IFRAME will often attempt to take over the browser or not function correctly.


Users with Edit permissions can edit the source of the RSS feed.  Click the  button to open the editor and supply values for the following attributes:


Target URL: This is the URL to the remote content to display in the module.

Height (Pixels): (Optional). This is the height in pixels of the rendered content.  It is often best to let the content auto-size.

Show Border: When checked a box will be drawn around the rendered content.

Scrolling Mode: Determines whether scrollbars are always displayed, never displayed, or allowed to auto-determine whether they should be displayed.

Description: This is a message that is displayed in browsers where IFRAME capabilities are disabled.
