Template Support in Vue Dashboard Layout component

30 Jul 2021 / 5 minutes to read

You can customize the default appearance of the dashboard layout using the content property.

The two ways to configure template support in dashboard layout using content property are:

  • Custom vue template (.vue file)
  • Vue.component()

Custom vue template

The content property is used to customize the default appearance of each panel in the dashboard layout. The content of the dashboard layout is displayed as per the template layout provided.

  • Define the content in a pietemplate.vue file and create an object data in the data option of the pietemplate.vue file.

Refer to the following code snippet of pietemplate.vue file.

  • Import the pietemplate.vue file in the corresponding app.vue file and create a template function, which returns an object

import pieTemplate from './pietemplate.vue'

pie: function () {
return { template : pieTemplate }
},

Refer to the following code snippet of App.vue file.

// App.vue

<template>
<div id="app">
 <!--  dashboard layout element declaration -->
  <ejs-dashboardlayout ref="DashbordInstance" :columns="2" id='edit_dashboard' >
     <e-panels>
             <!--  template declaration for content property -->
            <e-panel :row="0" :col="1" :sizeX="1" :sizeY="1" header="<div>Pie Chart</div>" :content="pie"></e-panel>

</ejs-dashboardlayout>
</div>
</template>
<script>
import Vue from 'vue';
// Import syncfusion dashboardlayout component from layouts package
import { DashboardLayoutPlugin } from "@syncfusion/ej2-vue-layouts";
import pieTemplate from "./pietemplate.vue";
import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);

Vue.use(DashboardLayoutPlugin);

export default {
   data () {
    return {
         pie: function () {
            return { template : pieTemplate }
        },
    };
 },
}
</script>

Vue component

The pietemplate is initialized with Vue.component() where template is provided in the template option.
