# Open dropdown menu

When you select a [Dropdown menu](https://docs.vivlab.com/en/editor/menu/menu.md) element on the canvas, the editor **automatically opens** the menu to display all its sub-items, as if they were already expanded for a visitor.

## When the menu closes

The menu stays open as long as it is **selected**. As soon as you click elsewhere on the canvas (on another block or in empty space), it automatically closes and resumes its normal visitor behavior.

This interaction is fully automatic: there's no button to enable. Select the menu, edit what you want from the [side panel](https://docs.vivlab.com/en/editor/menu/menu.md), then click elsewhere to see the visitor rendering.

::: info Why this auto-opening
Without it, you would only see the dropdown menu's button and it would be impossible to judge the formatting of sub-items (texts, descriptions, spacing). By forcing the opening during edit, the editor shows you live the result of every change made in the side panel.
