# Collections

> Track a project's links in a table or board with your own columns and saved views.

- Web page: https://documentation.federated.computer/superbrain/collections/

A collection is a project view over bookmarks you already have. You give the collection its own columns (called **properties**), such as Status, Owner, or Priority, and save **views** that filter and lay out the items as a table or a board.

Adding a bookmark to a collection doesn't copy it. The same bookmark can be in several collections at once, with different property values in each. Removing it from a collection, or deleting the whole collection, leaves the bookmark itself untouched.

## Create a collection

1. Open **Collections** in the sidebar.
2. Type a name in **New collection** and create it.
3. Select **Add bookmarks**, then search for existing bookmarks and add them.

## Add properties

Select **New property**, give it a name, choose a type, and select **Create property**. The types are:

| Type | Use it for |
|---|---|
| Text | Free text, such as a short summary |
| Number | Quantities, estimates, or scores |
| Select | One option from a list, such as a status |
| Multi-select | Several options from a list, such as labels |
| Date | A date, either date only or date and time |
| Checkbox | Yes/no, such as "reviewed" |
| URL | A second link, such as a related document |

For Select and Multi-select, add the options and choose a color for each.

> **Note**
>
> A property's type can't be changed later, so pick it carefully. This protects the values already entered.

Fill in properties by editing the cells in the table.

## Views

A view is a saved way of looking at the collection. It never copies records. Select **New view**, name it, and choose a type:

- **Table** shows items in rows with a column for each property.
- **Board** groups items into columns by a Select property, for example one column per status. Drag a card to another column to change its value.

To filter a view, select **Add a filter clause**, choose a property, an operator, and a value, then **Apply filter**. Filters are saved with the view, so each colleague can keep views like "My open items" or "Due this week".

## Share a collection

Select **Share collection**, search for colleagues by name or email, and share. They can view the collection and its items but can't change them. Select **Revoke** to stop sharing at any time; their access ends immediately. See [Sharing](../sharing/).

## Show a collection on a page

You can embed a live view of a collection in a [page](../pages/), for example to keep a project's status board next to its notes.

## If two people edit at once

If a colleague changes the same item, property, or view while you're working on it, Superbrain shows a conflict and doesn't overwrite their change. Reload and make your change again.
