# Synced Sections

> Create reusable sections, insert them into experiences, update them everywhere, and detach when needed in Introw.

**Open in Introw:** [Synced sections](https://app.introw.io/sections)

## How it works

Synced sections live alongside experiences in the experience builder. A synced section is a
saved content block you can insert into any experience. You can create one from scratch or save
an existing section from an experience as a synced section. Once inserted, an instance stays linked to
the saved section, so editing the saved section updates every place it is used.

When a single experience needs a different version, you detach that instance, which keeps a
local copy and breaks the link so further edits to the saved section no longer affect it.

## Prerequisites

* Write access to experiences and sections.

## Settings & configuration

Synced sections are managed under [Synced sections](https://app.introw.io/sections).

### Creating a synced section

Create an empty synced section and build it in the editor, or save an existing section from an
experience as a synced section so its content becomes reusable.

### Inserting into an experience

In an experience, add a synced section from the section picker. The inserted instance is linked
to the saved section.

### Editing

Open the saved section at its editor and edit it; changes propagate to the linked instances.
A linked instance in an experience points back to the saved section for editing.

### Detaching

Detach an instance to break its sync link and keep a local, independently editable copy in that
experience.

### Duplicating

Duplicating a section copies its content; if it embeds CRM views, those references are remapped
so the copy works on its own.

## Limits & gotchas

<Warning>
  Editing a saved section changes every linked instance, so review where it is used before making changes. Detaching is one-way for that instance: it no longer receives updates from the saved section. Publishing the experiences that use a section is still required for partners to see updates.
</Warning>

## Troubleshooting

* **An edit did not appear in a portal** - the instance was detached, or the experience was not published.
* **A change affected an unexpected portal** - the section is synced across more experiences than expected.
* **A duplicated section shows wrong CRM data** - confirm the CRM references were remapped on duplication.
