Correlated fields

The Correlated fields Answer Type allows you to repeat a block of answer fields, so Workers can dynamically add Answers. This feature is useful when the number of task answers is unknown, for example: "Find all members of the Board of Directors from an annual report".

Repeatable block creation

To create a repeatable answer block, select the Answer Type > Correlated fields when adding a new Answer.

Correlated fields options

Custom parameters are 6|Add more|Stack, where:

• 6: max block size; you can input any integer value.
• Add more: the name of the block creation button.
• Stack: one of three variants (tabs, stack, horizontal) for tabs location.

Default parameters are as follows:

• Max block size: unlimited
• Button name: Add
• Tabs location: Tabs

The worker's answer is processed as a pair of values divided by ::.

Usage

Used as a parent container for child answer types. Child answers should be non-adjudicated and in common case.

Currently supported child answers include the following:

• FREE_TEXT
• LONG_TEXT
• CHECK_ONE
• CHECK_MULTI
• SELECT_ONE
• SELECT_MULTI
• NUMBER
• PRICE
• DATE
• TIME
• PHONE
• EMAIL
• MASKED_TEXT
• SLIDER
• TEXT_LIMITATION_AREA
• UPC_CODE
• SELECT_DATE

For example, you can use the 3|Add|stack values to set the parameters, where:

• 3: first value, max block size
• Add: button name
• Stack: one of the three variants (tabs, stack, horizontal) for tabs location

Default parameters are as follows:

• Max block size: unlimited
• Button name: Add
• Tabs location: Tabs

Default value

The default value is a JSON object of the following structure:

{"cf":[{"t1":"b","t2":"b"},{"t1":"a","t2":"a"}]}

Where:

• cf is the correlated_field answer code.
• t1 is the first sub-answer.
• t2 is the second sub-answer.
• a and b are values.

Example

Below is an example of the default JSON object:

{"cf":[{"t1":"b","t2":"b"},{"t1":"a","t2":"a"}]}

Where:

• cf is a Correlated Input answer code that should be used in conjunction with CorrelatedMultivalueComparator.
