I am very curious to understand the difference between these two task/log a call layouts. Are they compact layouts? The task layout in the Opportunity detail page allowed me to add multi-picklist field on the layout, while the one for the Account layout did not. Is that possible to add a multi-pick list field on the compact layout? If yes, how can I achieve it.
Please clarify. Given below are the screenshots task/log a call layout on Account and Opportunity detail pages.
