# Collapsible blocks
Collapsible blocks are sections of content that can be expanded and collapsed, letting you hide detail until it's needed.

A collapsible block consists of:

*   **An always-visible header**, containing:
    *   **An arrow** that expands or collapses the block when clicked.
    *   **A summary line** that acts as the block's title. With the cursor in the summary line, press <kbd>Ctrl</kbd>+<kbd>Enter</kbd> to expand or collapse the block.
    *   **A drag handle** for repositioning the block within the note.
*   **The body**, which is hidden while the block is collapsed. It can hold any kind of content, including nested collapsible blocks. To break out of a collapsible block and continue typing outside it, press <kbd>Enter</kbd> twice at the end of the block.

You can use the arrow keys to move freely with the cursor between the summary line, the block's body, and the text around the block.

## Inserting a collapsible block

In the formatting bar, go to “**Insert” → “Collapsible Block”**.

> [!TIP]
> Place multiple collapsible blocks one after another to create an accordion, where each block can be expanded or collapsed independently.
