In PoolParty CardSorting the Brainstorming Phase is the first phase of the two-phases to create a new PoolParty Taxonomy. In this phase, users can define and vote for a concept. When you start a new session, there are no concepts yet, just like in the screenshot below. If you are returning to an old session and if that session already has concepts, those concepts are visible here.
Zoom In and Out
After a while this space might get a bit more crowded. To see the concepts better zoom in or out by using the slider (1).
Drag and Drop Concepts
If you want to create an initial taxonomy hierarchy or just want to sort them, you can drag and drop them by simply pointing your cursor at the concept and then by pressing the left mouse button to drag it to a new location.
