vue-typeahead

See a live demo here.

Install

NPM

Available through npm as vue-typeahead.

npm install --save vue-typeahead

Also, you need to install a HTTP client like axios.

Usage

If you are using vue@1.0.22+, you could use the new extends property (see below).
Otherwise, the mixins way also works.

      <i class="fa fa-search" v-show="isEmpty"></i>
      <i class="fa fa-times" v-show="isDirty" @click="reset"></i>

    <!-- the input field -->
    <input type="text"
           placeholder="..."
           autocomplete="off"

           @blur="reset"
           @input="update"/>

    <!-- the list -->

      <!-- for vue@1.0 use: ($item, item) -->
      <li v-for="(item, $item) in items" :class="activeClass($item)" @mousedown="hit" @mousemove="setActive($item)">
        <span v-text="item.name"></span>
      </li>
    </ul>
