List UI Node
This node helps to create a list of elements.
This node is used for providing the data to the list dynamically and for adding logic to various events. The main purpose of the node is to populate the list of items that you want to show repeatedly.
How to get List UI Node.
For creating a new List first you have to create a single element [repetitive element] of the list, this can be a single rectangle, text or a group with multiple items in it. The process remains the same for all types of list except when list element consists of a single rectangle or text then only one item widget is going to be generated while list node is created, but if the single list element consists of multiple items like a group then the number of item widget that going to be associated with list node is equal to the number of items present in the single group.
After the list element is created convert it to the list by clicking on the convert to list button in the properties panel, then select the list created and right-click on the list and choose "edit in blup lightning" in the arsenal .
As soon as you do that a listview node is generated in the blup lightning which consists of an automatically generated item widget based on the number of items in a single element of the list.
