Auto complete

You can get some recommended tips based on the current input.

::: demo Autocomplete component provides input suggestions. The fetch-suggestions attribute is a method that returns suggested input. In this example, querySearch(queryString, cb) returns suggestions to Autocomplete via cb(data) when suggestions are ready.

<el-row class="border-grid">
  <el-col :span="12" class="tac">
    <div class="text">list suggestions when activated</div>
    <el-autocomplete
      class="inline-input"
      v-model="state1"
      :fetch-suggestions="querySearch"
      placeholder="Please input"
      @select="handleSelect"
    ></el-autocomplete>
  </el-col>
  <el-col :span="12" class="tac">
    <div class="text">list suggestions on input</div>
    <el-autocomplete
      class="inline-input"
      v-model="state2"
      :fetch-suggestions="querySearch"
      placeholder="Please input"
      :trigger-on-focus="false"
      @select="handleSelect"
    ></el-autocomplete>
  </el-col>
</el-row>
<script>
  export default {
    data() {
      return {
        links: [],
        state1: '',
        state2: ''
      };
    },
    methods: {
      querySearch(queryString, cb) {
        var links = this.links;
        var results = queryString ? links.filter(this.createFilter(queryString)) : links;
        // call callback function to return suggestions
        cb(results);
      },
      createFilter(queryString) {
        return (link) => {
          return (link.value.indexOf(queryString.toLowerCase()) === 0);
        };
      },
      loadAll() {
        return [
          { "value": "vue", "link": "https://github.com/vuejs/vue" },
          { "value": "element", "link": "https://github.com/ElemeFE/element" },

         ];
      },
      handleSelect(item) {
        console.log(item);
      }
    },
    mounted() {
      this.links = this.loadAll();
