27 Sep 20232 minutes to read

Tooltip loads HTML pages via HTML tags such as iframe, video, and map using the content property, which supports both string and HTML tags.

To load an iframe element in tooltip, set the required iframe in the content of tooltip while initializing the tooltip component. Refer to the following code.

content= '<iframe src="https://www.syncfusion.com/products/essential-js2"></iframe>

app.component.ts

import { Component, ViewEncapsulation } from '@angular/core';
import { TooltipComponent } from '@syncfusion/ej2-angular-popups';

@Component({
    selector: 'my-app',
    template: `
       <div id="tooltipContent">
            <div class="content">
            <ejs-tooltip cssClass='e-tooltip-css' position='BottomCenter' opensOn='Click'>
                <!-- iframe element -->
                 <ng-template #content>
                 <iframe src="https://www.syncfusion.com/products/essential-js2"></iframe>
                </ng-template>
                <button ejs-button class="text" id="iframeContent" cssClass='e-outline' isPrimary=true>Embedded Iframe</button>
            </ejs-tooltip>
            </div>
        </div>`,
    encapsulation: ViewEncapsulation.None,
})

export class AppComponent {
}
