# Selection Manager

## Introduction

{% hint style="info" %}
Part of the [Selection System](/old-kb/toolkit-for-ui-and-ux/unity/learning/core-concepts/selection-system.md) of the UX Complete asset
{% endhint %}

This component simply exposes the selection changed event to the Unity Inspector and a selection of the common selection funcitons.

{% hint style="success" %}
Selection Manager is a .NET IColleciton of SelectableObjects ... this means you can iterate over it to iterate over the selected objects

```csharp
foreach(var selected in selectionManager)
{
    Debug.Log(selected.name + " is selected");
}
```

{% endhint %}
