Compose Collection

Creates a collection from a set of homogenous values. Each element of the collection is represented as an input pin and the created collection is represented as a single output pin. The size and the type of the collection is an editable property of the block. Users can show or hide the available input pins (Figure 1).

Note: The type of the created collection can be a different type of generic IList implementation.

Visible Pins	You can check which elements should be visible (Figure 2).
