How Actions Are Ordered in the Salesforce App Action Bar
| Available in: both Salesforce Classic and Lightning Experience |
| Available in: Group, Professional, Enterprise, Performance, Unlimited, Contact Manager, Database.com, and Developer Editions |
If you customize the Salesforce Mobile and Lightning Experience Actions section of a layout, the app reflects your customizations.
If you customize the Quick Actions in the Salesforce Classic Publisher section, but not the Salesforce app section, the actions in the app action bar are a combination of those in the Quick Actions in the Salesforce Classic Publisher section plus any standard or custom buttons present on the page layout.
If you customize the Salesforce Mobile and Lightning Experience Actions section, the standard and custom buttons in the buttons section of the page layout aren’t automatically included in the action list. You must add the buttons as actions from the Mobile & Lightning Actions category in the palette.
If neither section is customized, the action bar inherits a default set of actions predefined by Salesforce. The sets of actions differ between objects, based on the most common or typical activities required for each object.
