Adding Syncfusion AutoComplete package in the application

Syncfusion Vue packages are maintained in the npmjs.com registry. The AutoComplete component will be used in this example. To install it use the following command.

Adding CSS reference for Syncfusion Vue AutoComplete component

Import the needed css styles for the AutoComplete component along with dependency styles in the <script> section of the src/App.vue file as follows.

<style>
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";

Adding Syncfusion Vue AutoComplete component in the application

You have completed all the necessary configurations needed for rendering the Syncfusion Vue component. Now, you are going to add the AutoComplete component using following steps.

Import the AutoComplete component in the <script> section of the src/App.vue file.

<script>
import { AutoCompleteComponent } from "@syncfusion/ej2-vue-dropdowns";
</script>

import { AutoCompleteComponent } from "@syncfusion/ej2-vue-dropdowns";
//Component registeration
export default {
name: "App",
components: {
 'ejs-autocomplete' : AutoCompleteComponent,
}
}

Add the component definition in template section.

<template>
<div class="control_wrapper">
    <ejs-autocomplete :dataSource='sportsData' :placeholder="waterMark"></ejs-autocomplete>
</div>
</template>

Summarizing the above steps, update the src/App.vue file with following code.

<template>
<div class="control_wrapper">
    <ejs-autocomplete :dataSource='sportsData' :placeholder="waterMark"></ejs-autocomplete>
</div>
</template>
<script>
import { AutoCompleteComponent } from "@syncfusion/ej2-vue-dropdowns";
//Component registeration
export default {
name: 'App',
components: {
    "ejs-autocomplete": AutoCompleteComponent
},
data () {
    return {
        waterMark : 'e.g. Basketball',
        sportsData: ['American Football', 'Badminton', 'Basketball', 'Cricket',
            'Football', 'Golf', 'Gymnastics',
            'Hockey', 'Rugby', 'Snooker', 'Tennis'
        ]
    }
}
}
</script>

Running the application

Run the application using the following command.

npm run serve

Custom values

The AutoComplete allows the user to give input as custom value which is not required to present in predefined set of values. By default, this support is enabled by allowCustom property. The custom value will be sent to post back handler when a form is about to be submitted.

<template>
<div id="app">
    <ejs-autocomplete :dataSource='sportsData' :placeholder="waterMark" ></ejs-autocomplete>
  </div>
</template>
<script>
import { AutoCompleteComponent } from "@syncfusion/ej2-vue-dropdowns";
//Component registeration
export default {
name: 'App',
components: {
    "ejs-autocomplete": AutoCompleteComponent
},
data () {
    return {
        waterMark : 'Find a game',
        sportsData: ['Badminton', 'Basketball', 'Cricket',
            'Football', 'Golf', 'Gymnastics',
            'Hockey', 'Rugby', 'Snooker', 'Tennis'
        ]
    }
}
}
</script>
<style>
@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-vue-dropdowns/styles/material.css";
  #app {
color: #008cff;
height: 40px;
left: 35%;
position: absolute;
top: 35%;
width: 30%;
  }
</style>

Configure the suggestion list

By default, suggestion list width automatically adjusts according to the AutoComplete input element’s width, and the height of the suggestion list has ‘300px’. The height and width of the popup list can also be customized using the popupHeight and popupWidth property respectively. In the following sample, suggestion list’s width and height are configured.

<template>
<div id="app">
    <ejs-autocomplete :dataSource='sportsData' :popupHeight='height' :popupWidth='width' :placeholder="waterMark" ></ejs-autocomplete>
  </div>
</template>
<script>
import { AutoCompleteComponent } from "@syncfusion/ej2-vue-dropdowns";
//Component registeration
export default {
name: 'App',
components: {
    "ejs-autocomplete": AutoCompleteComponent
},
data () {
    return {
        waterMark : 'Find a game',
        allowCustom: true,
        height: '250px',
        width: '250px',
        sportsData: ['Badminton', 'Basketball', 'Cricket',
            'Football', 'Golf', 'Gymnastics',
            'Hockey', 'Rugby', 'Snooker', 'Tennis'
        ]
    }
}
}
</script>
<style>
@import "../../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-inputs/styles/material.css";
@import "../../node_modules/@syncfusion/ej2-vue-dropdowns/styles/material.css";
  #app {
color: #008cff;
height: 40px;
left: 35%;
position: absolute;
top: 35%;
width: 30%;
  }
</style>
