+## AJAX Remote Option Loading
+
+[](codepen://sagalbot/POMeOX?height=400)
+
+The `onSearch` prop allows you to load options via ajax in a parent component 
+when the search text is updated. It is invoked with two parameters, `search` & `loading`.
+
+```js
+/**
+* Accepts a callback function that will be run
+* when the search text changes. The callback
+* will be invoked with these parameters:
+*
+* @param {search}  String		Current search text
+* @param {loading} Function	Toggle loading class
+*/
+onSearch: {
+  type: Function,
+  default: false
+},
+```
+
+The `loading` function accepts a boolean parameter that will be assigned 
+to the vue-select internal `loading` property. Call `loading(true)` to set the 
+`loading` property to `true` - toggling the loading spinner. After your 
+asynchronous operation completes, call `loading(false)` to toggle it off.  
+
+#### Disabling Filtering
+
+When loading server side options, it can be useful to disable the 
+client side filtering. Use the `filterable` prop to disable filtering.
+
+```js
+/**
+ * When true, existing options will be filtered
+ * by the search text. Should not be used in
+ * conjunction with taggable.
+ * 
+ * @type {Boolean}
+ */
+filterable: {
+	type: Boolean,
+	default: true
+},
+```
+
+#### Loading Spinner
+
+Vue Select includes a default loading spinner that appears when the loading class is present. The `spinner` slot allows you to implement your own spinner.
+
+```html
+<div class="spinner" v-show="spinner">Loading...</div>
+```
+
+#### Library Agnostic
+
+Since Vue.js does not ship with ajax functionality as part of the core library, it's up to you to process the ajax requests in your parent component.
+
+I recommend using [axios](https://github.com/axios/axios) for creating your applications HTTP layer, 
+or [`fetch()`](https://github.com/github/fetch) for simple requests.
