Built-in property types

This topic describes how to use built-in property types in your models and also create your own property types.

Optimizely CMS content is built-up by models with properties that store and present data. You can use many built-in property types in your models and also create your own property types.

Common property types

What you want to createSolutionEditing experienceHints and tips
Plain short textString propertyOne row inputControl the allowed length with the StringLength attribute. Use custom tag to control the containing tag, such as using a H1 for the main header for the page.
Plain long textString property with UIHint.TextareaText areaControl the allowed length with the StringLength attribute.
HtmlXHtmlString propertyA TinyMCE HTML editor 
Integer valueInt propertyA number sliderControls other rendering, such as the number of items in a list. Control the min and max values with the Range attribute.

BooleanBoolean propertyCheck box 
Page typePageType property Filter items in a list, and so on.
BLOB Blob property Hold binary data (such as an image). Route to a BLOB with pattern <Url to content>/BlobPropertyName.

Working with other content

To refer to existing content, use the Link or LinkCollection to create internal or external links.

  • Use ContentArea to display content from other content.
  • Use ContentReference, ContentReferenceList, or URL to link to a single content of a specified type.
  • Use the AllowedTypes attribute to further restrict the kind of links that are possible to add to a property, (although there are a few known limitations).

Use a content reference with many different UI hints to select different entities in Optimizely CMS, such as a block, a media item, a block folder, or a media folder.

Each link can be an item inside Optimizely CMS, such as pages or media but also external URLs. Use URL instead of ContentReference if you want to add information, such as query string parameters to control size.

Selecting predefined values

You can use the following solutions to create drop-down lists and check box lists:

What you want to createSolutionEditing experienceHints and tips
Select a single item from a relatively short list of optionsString/Int property with SelectOne attributeLink to implementation
page
 
Select several items from a relatively short list of optionsString/Int property with SelectMany attributeLink to implementation
page
 
Select a single item from a relatively long list of optionsString/Int property with AutoSuggestion attributeLink to implementation
page
Use with caution because the auto-suggestion editor creates requests to the server.

Validation attributes

Optimizely CMS supports the following validation attributes that are part of the .NET:

  • Range
  • StringLength
  • RegularExpression
  • EmailAttribute

You can create custom attributes that implement either ValidationAttribute. See Writing custom attributes.
