Create a Dynamic Actions Bar for Your App Page (Pilot)
How: To add a Dynamic Actions Bar to your Lightning app page, first create or edit a Lightning app page in the Lightning App Builder.
In the Lightning App Builder, drag the Dynamic Actions Bar component (1) to add it to a region on your page (2). The order of actions in the properties pane (3) determines their order in the Dynamic Actions Bar. Click Add Action (4) to add actions to the Dynamic Actions Bar. Click Add Filter (5) to set visibility filters for the Dynamic Actions Bar component. Save your work.
If the page isn’t already active, click Activation and select an activation option for the page.
