# Subsessions
> Group sessions inside a parent session, such as talks in a breakout block, and choose how they show in the app.

Subsessions let one session hold others, such as a breakout block with three talks, or a poster session with each poster inside it. Attendees see the parent in the schedule with its subsessions listed under it.
To turn them on, open **Schedule settings** and turn on **Enable subsessions**. A **Subsessions** column appears in the schedule.
## Add a subsession
On the parent session's row, click **Add** in the **Subsessions** column.
Fill in the subsession like any other session, then click **Save**. By default it takes the parent's date, time, track and room, so you only need a **Title**.
Subsessions appear under their parent in the schedule. Click the arrow next to the parent's title to show or hide them. The **App preview** shows how attendees see them.
When you open a subsession, the **Parent session** card at the top of its drawer shows the parent's title and time. **Inherit time & room from the parent session** is on by default. Turn it off to give the subsession its own time and room, such as a talk that starts halfway through the block.
## Move a subsession
Open the subsession and click **⋯** on the **Parent session** card:
- **Move to another parent**: choose a different parent session. This is also in the **⋯** menu on the subsession's row.
- **Convert to parent session**: take it out of its parent, so it becomes a session of its own.
To put an existing session inside another, click **⋯** on its row and choose **Move under a parent**. A session that already has subsessions can't go inside another one: subsessions are one level deep.
Deleting a parent session also deletes its subsessions.
## Subsession settings
Click **Configure** under **Enable subsessions** to set how subsessions behave:
| Setting | What it does |
| --- | --- |
| **Keep subsessions within the parent's time** | When a subsession has its own time outside the parent's slot, **Warn** you, or **Block** saving it (the default). |
| **Fields inherited by default** | What new subsessions take from the parent until you change them: **Time**, **Track**, **Location** and **Speakers**. Click a field to switch it on or off. |
| **Link speakers to the parent** | Adding a speaker to a subsession also adds them to the parent session. |
| **Order subsessions** | Sort subsessions **By time**, or **Manual** to drag them into your own order. |
| **Expand subsessions by default** | Show every subsession in the app schedule. Turn it off to fold them under the parent, which attendees tap to open. This keeps long agendas tidy. |
