openSubtab() for Lightning Experience

Opens a subtab within a workspace tab. If the subtab is already open, the subtab is focused. This method works only in Lightning console apps.

Arguments

Name	Type	Description
parentTabId	string	The ID of the workspace tab within which the new subtab opens.
pageReference	object	Specifies the pageReference to open. pageReference is optional.
recordId	ID	Specifies the record to open. recordId is optional.
url	string	The URL representing the content of the new workspace tab. url is optional. The URL can be either relative or absolute. To use a third-party domain, add the site as a CSP Trusted Site.
focus	boolean	Specifies whether the new subtab has focus. To display the subtab immediately, set focus to `true`. To open the subtab in the background, set focus to `false`.

pageReference, recordId, and url are prioritized in that order. Providing arguments with a higher priority means the others will be ignored.
