🔲Slot

Slots are containers for anything that you want to re-use across your site, like a nav menu.

Slots enable you to create reusable sections on your site. Changes made to one instance of the Slot will automatically change all other instances.

Slots and their children will appear purple in the navigator and canvas to indicate they are Slots, and any changes made to them will affect all other instances of the Slot.

Slots are most commonly used to create reusable navigations and footers, though they are helpful for any sections you want to reuse throughout your site.

Data variables defined on the Global Root are accessible within Slots, while those defined on other instances outside the Slot are not.

How to use Slot component

Here is the process for creating and reusing Slot instances:

Creating a Slot instance

Slot component and its source content on the canvas

1. You can find the Slots component in the “Components Panel.”

2. Drag “Slot” from the Components Panel onto your canvas to create a Slot instance. Alternatively, you can add it to the currently selected instance with a click.

3. Add other instances from the Components Panel into the Slot instance to populate it.

Reusing a Slot instance

Once you have a Slot on the canvas you can re-use it by simply copying and pasting it anywhere in your project.

1. Select your Slot instance and press Ctrl + C (for Windows) or CMD + C (for Mac).

2. Now, select the position where you want to insert the Slot instance and press Ctrl + V (for Windows) or CMD + V (for Mac)

And that’s it! Now updates that you make to any Slot will update all other instances of that Slot.

If you need a new unique Slot instance, simply add a new Slot from the Add panel and it will not interfere with your existing Slots.

Create shared Slots with AI agents

Webstudio MCP can convert an existing section into a shared Slot and insert linked copies elsewhere in the Project. The agent can also add another copy of an existing Slot to a different page. Every copy points to the same shared content, so later edits remain synchronized in the Builder.

Ask the agent to inspect the target parent before inserting a Slot. Webstudio validates component nesting, prevents a Slot from being inserted inside its own content, and rejects ambiguous instance paths instead of guessing which shared occurrence to change.

Conclusion

With Slots you can re-use content across your site and sync the changes you make to them.
