Custom Properties
Use Custom Properties to define and add different custom metadata types to an asset.

First, create a property from the “Manage Custom Properties” UI to use Custom Properties. To open the “Manage Custom Properties” UI, go to Settings > Custom Properties:
There are two custom property types - shared and nonshared. The shared property type allows you to predefine multiple values members can choose from when adding the property to an asset. An “Author" property with a predefined list of authors would be a good example. 

The other nonshared property type allows you to define a property where users can add custom values when using it. For example, you can create a "Due date" property users can use to choose any date when adding it to an asset. 

Creating a new Shared Property

To create a new shared property, click the "SHARED" button to open the "Add new shared property" UI:
To add the new property, you must give it a name, choose the property type, and add property values. There are three property types available: Short text, Number and Date:

Creating a new Non-Shared Property

To create a new nonshared property, click the “NON-SHARED" button to open the "Add new non-shared property" UI:
In addition to the Short text, Number and Date types available for the shared property, the non-shared property has two more types: Text block and Checkbox. The first allows the users to type in larger text content, and the latter adds an "on / off" checkbox: 
In contrast with the shared property, you don't define shared values when adding a non-shared property since the users will be adding custom values on the individual assets using this non-shared property. 

Editing Custom Properties

Once added, you can edit a custom property by first clicking the "edit" button next to the property name in the properties list of the "Manage Custom Properties" UI.  
For the shared and non-shared properties, you can edit the name and cannot change the property type. In addition, you can add new property values and change or delete already added ones for the shared properties.   
To delete a property, click the "delete" button next to the property name in the list.

Using Custom Properties with assets

To add a custom property to a selected asset, go to the Custom Properties section of the Details Panel and click on the "Type in to add property..." field. From the list of all available custom properties, click on the ones you want to add to the asset. 

Use the "Type in to add property..." field to filter the properties list quickly: 
  1. Start typing in.
  1. Choose a property from the dropdown.
  1. Press the Escape keyboard button or click the "x" button to reset the filter.
  1. Start typing again if you want to choose another property. 

To add custom properties simultaneously on multiple assets:
  1. Click on the "Add custom property" command in the asset's contextual menu.
  1. Type into the field to choose from the available properties.
  1. Select a property, choose the needed value if it's a shared property or define the value if it's a non-shared property.
  1. Click the Add button. 

To remove a custom property, click on the "x" button in the top right corner of the Custom Properties section, then click on the "x" button next to the property you want to remove:
