I want to display an icon in a formula field based on the value in another checkbox field on my object. I would like to use the standard Lightning SLDS icons here. I've found a way to achieve this using static resources.
I downloaded the icon I needed from https://www.lightningdesignsystem.com/downloads/ and uploaded it as a static resource. The formula markup is as follows and works correctly to display the icon when the checkbox is true, and display nothing if the checkbox is false:
IF(MyCheckbox__c, IMAGE( LEFT( $Api.Partner_Server_URL_260, FIND('/services',$Api.Partner_Server_URL_260) ) + "resource/MyIconResource", "MyIconResource", 25, 25) , '' )
My question is, is there any way to access the standard SLDS Lightning icons in a formula field without having to using static resources, perhaps by accessing a URL for an icon directly from the formula?
