+## Introduction
+
+The [Checkbox radio selector](https://marketplace.mendix.com/link/component/000) widget displays a list of options that users can select from. This is useful in scenarios where end-users need to select their data through choices, such as being able to select or de-select different enumeration list.
+The widget will automatically display a check box list for multi selection and radio button list for single selection with exception for boolean datasource, where user can choose the render type.
+
+### Features
+
+* Supports different data sources:
+    * Context:
+        * Association
+        * Enumeration
+        * Boolean
+    * Database lists
+    * Static values
+* Supports custom content rendering
+* Supports custom footers
+
+{{% alert color="info" %}}
+This widget does not have lazy loading and pagination feature. If user need to display a lot of options, it is recommended to use [combobox](/appstore/widgets/combobox/) instead
+{{% /alert %}}
+
