UXML element ScrollView

ScrollView displays its content inside a scrollable area. When you add content to a ScrollView, the content is added to the content container (#unity-content-container) of the ScrollView.

Manage the scroll bar visibility

You can specify the direction of the scroll bar movement, whether the horizontal or vertical scroll bars are visible, and control the speed of the scroll bars.

To set the direction of the scroll bar movement in UI Builder, in the Inspector window of the ScrollView, select one of the following options for Mode:

• Vertical (default)
• Horizontal
• Vertical and Horizontal

To set the visibility of the scroll bar in UI Builder, in the Inspector window of the ScrollView, select one of the following options for Horizontal Scroller Visibility or Vertical Scroller Visibility:

• Auto (default)
• Always Visible
• Hidden

To control the speed of the scroller in UI Builder, in the Inspector window of the ScrollView, select one of the following options for Horizontal Page Size or Vertical Page Size and enter a number. The greater the number you enter, the faster the speed of the scroller will be.

Wrap elements inside ScrollView

You can wrap visual elements inside a ScrollView so that the elements display in a row. If the row is full, the elements continue to display on the next line.

To wrap visual elements inside a ScrollView, set the ScrollView’s content container flex direction to Row and flex wrap to Wrap.

In USS:

.unity-scroll-view__content-container {
    flex-direction: row;
    flex-wrap: wrap;
}

In C#:

scrollview.contentContainer.style.flexDirection = FlexDirection.Row;
scrollview.contentContainer.style.flexWrap = Wrap.Wrap;

Wrap text of elements inside ScrollView

To wrap the text of an element inside a ScrollView, for example, the text of a Label element, do the following:

1. Style the Label element with any of the following methods:
   • In UI Builder, in the Inspector window of the Label, select Text > Wrap > normal.
   • Apply style white-space: normal; to the Label element in USS, UXML, or C#.
2. Create a VisualElement as a container inside the ScrollView. The original container element inside the ScrollView does not have bounds set (is infinite in size), so text won’t properly wrap. This container VisualElement provides the finite size for text to wrap within.
3. Add the Label to the VisualElement container.
