+# Icon Selection Editor for EPiServer.
+
+Module which extends EPiServer edit mode by adding possibility to select icons (i.e. [Font Awesome](https://fontawesome.com/), [Materialize](https://materializecss.com/), [CSS.gg](https://css.gg/) etc.) using dropdown.
+
+![](docs/fa.gif)
+
+## How to create and use IconSelectionEditor.
+
+1. Create model class which will represent icon:
+```csharp
+public class CustomIconSelectItem : IconSelectItem
+{
+    public override string ToHtmlString()
+    {
+        (...)
+    }
+}
+```
+
+2. Create IconSelectionFactory which will return all available icons:
+```csharp
+public class CustomIconSelectionFactory : IconSelectionFactory
+{
+    public override IEnumerable<IconSelectItem> GetIcons(ExtendedMetadata metadata)
+    {
+        (...)
+    }
+}
+```
+
+3. Create property attribute:
+```csharp
+public class SelectCustomIconAttribute : SelectIconAttribute
+{
+    public SelectCustomIconAttribute()
+    {
+        this.SelectionFactoryType = typeof(CustomIconSelectionFactory);
+        this.SelectionGridWidth = "580px";
+    }
+}
+```
+
+4. Decorate EPiServer content model property using created custom attribute:
+```csharp
+[ContentType(DisplayName = "Custom Content Block", GUID = "d1216b39-21ce-4873-a8c1-c3d5db2b9285")]
+public class CustomContentBlock : BlockData
+{
+    [SelectCustomIcon]
+    public virtual string Icon { get; set; }
+}
+```
