+#### Selectable picker
+
+Selectable picker added in #253 and allows using `Picker` component as a selector to select and unselect a single emoji.
+
+Here is an example:
+
+```javascript
+<template>
+  <div>
+  <emoji v-if="selectedEmoji" :data="index" :emoji="selectedEmoji" :size="32" />
+  <picker
+    :data="index"
+    :emoji="selectedEmoji"
+    :selectable="true"
+    @select="selectableSelectEmoji"
+    @unselect="selectableUnselectEmoji"
+  />
+  </div>
+</template>
+
+<script>
+import data from 'emoji-mart-vue-fast/data/all.json'
+import 'emoji-mart-vue-fast/css/emoji-mart.css'
+import { Picker, Emoji, EmojiIndex } from 'emoji-mart-vue-fast'
+
+export default {
+  data() {
+    return {
+      index: new EmojiIndex(data),
+      emoji: 'point_up',
+      selectedEmoji: undefined,
+    }
+  },
+  methods: {
+    selectableSelectEmoji(emoji) {
+      this.selectedEmoji = emoji
+    },
+    selectableUnselectEmoji(emoji) {
+      this.selectedEmoji = undefined
+    },
+  },
+  components: {
+    Picker,
+    Emoji,
+  },
+}
+</script>
+```
+
 #### Picker Usage And Native Emoji vs Images
 
 The `select` event described above can be handled to insert the emoji into the text area or use it in any other way.
