Object Properties
Object properties let you link a property to an object type using a dropdown. You select from a predefined object type and can customize the property to support single or multiple selections, two-way syncing, and fixed sets.
INFO
Single-select and multi-select have been merged into a single ‘Object Select’ property option in the menu when creating a new property.
Set Up
To add an object property, click + New Property and choose the object type you want to link to.
Example: Add an “Author” property to a Book object that links to the Person object type. This creates a dropdown of all people in your space.
By default, the property allows selecting multiple objects from the linked type, with no restrictions.
To limit selection to a single object or a specific set of objects, see the Customizations section below.
Customizations
Single vs. Multiple Selection
Go to the property settings and find the ‘Single or multi select’ section.
Choose: • Single Object — only one object can be selected
• Multiple Objects — switch back any time if needed
Fixed Set (Custom Dropdowns)
Use a Fixed Set to limit the dropdown to specific objects.
This is useful for controlled categories like: • Ratings • Priorities • Media types • Meeting note types
For new properties:
• Click Fixed Set during setup
• Each object you link grows the dropdown list organically. For example your list of statuses will grow as you add more statuses.
For existing properties:
• Go to Property settings > Enable fixed set > Fixed set > Calculate fixed set
• You must click Calculate or all current selections will be cleared
WARNING
After changing settings, always click Apply. Changing to a fixed set or altering selection limits may remove previously selected items from your content.
FAQs
Can I change the linked object type?

No. Use a text property for that. Learn more
Can I switch between single and multi-select?
Yes. Switch modes in the property settings. Be aware that switching to single-select may remove items if multiple were selected.
