 # ion-item-group
 
+Item groups are containers that organize similar items together. They can contain item dividers to divide the items into multiple sections.
 
+```html
+<ion-item-group>
+  <ion-item-divider>A</ion-item-divider>
+
+  <ion-item>
+    <ion-label>Angola</ion-label>
+  </ion-item>
+  <ion-item>
+    <ion-label>Argentina</ion-label>
+  </ion-item>
+  <ion-item>
+    <ion-label>Armenia</ion-label>
+  </ion-item>
+</ion-item-group>
+
+<ion-item-group>
+  <ion-item-divider>B</ion-item-divider>
+
+  <ion-item>
+    <ion-label>Bangladesh</ion-label>
+  </ion-item>
+  <ion-item>
+    <ion-label>Belarus</ion-label>
+  </ion-item>
+  <ion-item>
+    <ion-label>Belgium</ion-label>
+  </ion-item>
+</ion-item-group>
+```
+
+They can also be used to group sliding items:
+
+```html
