You can now add Dynamic Lists to your questions in Discover. Dynamic Lists enable you to construct lists on-the-fly based on instructions that you provide. The powerful thing about this is that lists can be unique and specific to each respondent's selections.
The most common implementation of Dynamic Lists is bringing items from one question into another based on a respondents selections—this function is called "Carry Forward Items."
To create a dynamic list open the list menu on a question or the list manager, click the "Create dynamic list" button (icon of a lightning bolt and a plus sign) on the Source List (parent) that the new Dynamic List will be based off of, then fill out the instruction settings.
To learn more about all the different function types and how to effectively use Dynamic Lists, be sure to check out our help documentation on Dynamic Lists.
