Template:Collapsible Section

This template makes a collapsible section with basic formatting, including an optional title. It:

• Leaves the title (if any) visible when the content is collapsed
• Uses the "mw-collapsible" components explicitly to keep the toggle button from drifting into any subsequent text (mw-collapsible-toggle-placeholder and particularly mw-collapsible-content.)

Write: {{Collapsible Section|my content|my title}}
to get:
(borders for demo only)

my title

my content
