Custom popup style

By default dropdown popup uses Dropdown control properties such as Background Color, Border Color, etc. to display a list of items to select from. But in many cases, games might want to customize this popup. To do so you can override one or more of the following functions in custom Dropdown implementation:

• CreatePopup
• CreatePopupRoot
• CreatePopupBackground
• CreatePopupItem

Here is an example dropdown implementation that adds the blur panel to the dropdown popup background:

public class DropdownWithBlur : Dropdown
{
    [EditorOrder(0), Limit(0, 100, 0.1f)]
    public float BlurStrength = 10.0f;

    public DropdownWithBlur()
    {
        // Remove background
        BackgroundColor = Color.Transparent;
    }

    protected override void CreatePopupBackground(DropdownRoot popup)
    {
        // Insert blur panel that will smooth background
        var blur = new BlurPanel
        {
            BlurStrength = BlurStrength,
            AnchorPreset = AnchorPresets.StretchAll,
            Offsets = Margin.Zero,
            Parent = popup.MainPanel,
        };

        base.CreatePopupBackground(popup);
    }
}
