Organize Components into Collapsible Sections
Manage screen clutter by grouping components into collapsible sections. The new Accordion component is like the Tabs component, but vertically stacked. You can use the Accordion component on all record pages. This feature is new in Lightning Experience.
You can have up to 25 sections, but we recommend no more than 10. You can also embed multiple components in each section, each with its own heading.
Here’s what the component looks like in the Lightning App Builder.
