Overview

Choice Field is a multi-purpose field used to allow the user to choose one or more options. It can be rendered as a select tag, radio buttons, or checkboxes.

Details

Choice field as a dropdownlist can be used just the same as a common html select. The options could have the standard properties like selected, disabled, label and value. Value and label properties and the text of the option could be localized.

The chosen option is indexed in the fulltext index by all its localized values and texts (so you can search by value or text) and indexed in field index by its value. If you wanna sort list items by a choice field, they will be ordered by the selected options value and the items with extravalue will be at the end of the list.

Enum options

The choice field can be built up using an Enumeration defined in source code.

<Options>
  <Enum type="SenseNet.Search.FilterStatus" resourceClass="MyResourceClassName" />
</Options>

In that case, you do not have to modify the CTD to localize the options of the field.
