Randomizing and anchoring options

List items can be shown in a randomized order to minimize respondent bias. Additionally, items can be anchored in specific positions. When the randomize tag is used on a list, all elements are displayed in random order. When the anchor decorator is added next to a list element, the item remains fixed in its position, regardless of any other ordering applied.

'randomize' tag

• The randomize tag accepts 'y' and 'n' inputs.
• randomize: y is the functional equivalent of order: [*]. 
• The randomize tag may be applied at either the list level or question level. If applied at the list level using a setlist, the same randomized order will occur for a respondent for every question (or table) where the list is used. When the randomize tag is included inline at the question level, all list elements will be randomized for that question only.
• The randomize tag can be paired with the anchor decorator to keep specific options anchored in their list positions.
• The randomize tag can be used as a decorator or as a column header in a spreadsheet to randomize collections organized by collection headers.

'anchor' decorator

• The anchor decorator accepts 'y' and 'n' inputs.
• anchor: y functions the same as using shorthand notations with '^' or '$' in the order tag.
• The anchor decorator may be applied at either the list level or question level. If applied at the list level using a setlist, the list element is anchored in every question (or table) where the list is used. When the anchor decorator is included inline at the question level, the list element is anchored for that question only.
• The anchor decorator can be used as a column header in a spreadsheet to anchor list items grouped by collection headers.
• For r9+, if a question or table uses the randomize or order tag and also includes a single exclusive option, that option is automatically anchored to the bottom of the list. The anchor decorator is not needed. For prior versions of the software, simply add the anchor decorator next to the exclusive decorator. 
• For r9+, if a question or table uses the randomize or order tag and also includes autoother options, these options are automatically anchored to the bottom of the list. The anchor decorator is not needed. For prior versions of the software, simply add the anchor decorator next to the autoother decorator.
