Parameters

Usage considerations

Displaying links

• To display a single link or array of links, put safe links inside of the link component.
• To display a link in a grid, put the safe link inside of a grid text column.
• To add a link to an image, put the safe link inside a document image or web image.
• To add a link to a chart series, put the safe link inside a chart series component.

Specifying URI protocols and using telephone links

• It's recommended that the URI use a specific protocol. When no protocol is specified, the component will generate a hyperlink using the system's protocol and domain.
• The telephone link URI ("tel:") is supported on the Appian Mobile application. If a user clicks this link in the application, the link will open a mobile device's default phone dialer.
• Telephone links may work in a web browser, but behavior can differ based on operating system and whether any telephone supported applications or extensions are installed.

Opening links in new tabs & windows

• A link created by a!safeLink() opens in a new tab by default. Opening a link in the same tab can be configured using the openLinkIn parameter.
• Note that a user's browser may still be configured so that new tabs are instead opened as new windows.
