Conditional map pin colour, using the Maps block. i.e. this, but in the Maps Block: https://toolset.com/forums/topic/toolset-maps-pin-colours/
Is it possible without resorting to legacy shortcodes?
Hello. Thank you for contacting the Toolset support.
No - there is no way to display different map marker using block. You will have to use the marker shortcode as described with the reference ticket you shared with the conditional shortcode.
