UI Dynamic Layout Component
With the DynamicLayout component, you can change the number of children of the layout element at run time. To use the DynamicLayout component, you place it on an element that also has a LayoutColumn , LayoutRow , or LayoutGrid component.
The layout element (1) dynamically resizes to fit its child elements. The first child (2) of the layout element acts as the prototype element. At run time, the UI system clones the prototype element to achieve the specified number of children in the layout.
The automatic resizing of the layout element depends on the layout type.
For a LayoutGrid element, the cell size of the LayoutGrid component determines the size of the child elements. The LayoutGrid element’s initial size determines the number of children that can fit in each row or each column, depending on fill direction or Order settings. If the Starting with fill direction is horizontal, the UI system uses the LayoutGrid element’s initial width to determine how many children fit in each row. If set to vertical, the initial height is used to determine how many children fit in each column.
To use a dynamic layout component
In the UI Editor , add a LayoutRow, LayoutColumn, or LayoutGrid prefab. To do this, choose New, Element from Prefab. Then select one of the layout elements.
This serves as the structure or framework to hold your dynamic content.
Add a DynamicLayout component to your layout component. To do this, in the Properties pane choose Add Component, DynamicLayout.
For Num Cloned Elements, enter the initial number of children to be created.
Create a child entity that has an Image component. To do this, right-click your layout component in the Hierarchy pane and choose New, Element from Prefab, Image.
This image serves as the prototype element that will be cloned and filled with dynamic content.
