Specifying the Content Template
The template implementation depends on the used framework or library. Examples of jQuery, Angular, and ASP.NET MVC are presented below. They show how to create a template consisting of static (text) and dynamic (the Switch widget) content.
jQuery
JavaScript
HTML
$(function() {
$("#tooltipContainer").dxTooltip({
target: "#image",
showEvent: 'dxhoverstart',
contentTemplate: function (contentElement) {
contentElement.append(
$("<p />").text("Static content"),
$("<div />").attr("id", "switchContainer").dxSwitch({
// The "Switch" widget is configured here
})
)
}
});
});<img id="image" src="https://url/to/an/image" /> <div id="tooltipContainer"></div>
Angular
HTML
TypeScript
<img id="image" src="https://url/to/an/image" />
<dx-tooltip
target="#image"
showEvent="dxhoverstart"
contentTemplate="tooltipContent">
<div *dxTemplate="let data of 'tooltipContent'">
<p>Static content</p>
<dx-switch>
<!-- The "Switch" widget is configured here -->
</dx-switch>
</div>
</dx-tooltip>
import { DxTooltipModule, DxSwitchModule } from "devextreme-angular";
// ...
export class AppComponent {
// ...
}
@NgModule({
imports: [
// ...
DxTooltipModule,
DxSwitchModule
],
// ...
})Vue

<dx-switch>
<!-- The "Switch" widget is configured here -->
</dx-switch>
</template>
</DxTooltip>

</text>)
)
<img id="image" src="https://url/to/an/image" />Switching Templates On the Fly
If you need to render different templates depending on a specific condition, define them inside the Tooltip container using the DevExtreme dxTemplate markup component. You can switch the templates on the fly by changing the contentTemplate option's value.

<p>First template</p>
</div>
<div data-options="dxTemplate: { name: 'template2' }">

</div>
</div>$(function() {
const tooltip = $("#tooltipContainer").dxTooltip({
target: "#image",
showEvent: 'dxhoverstart',

contentTemplate: 'template1'
}).dxTooltip("instance");
$("#buttonContainer").dxButton({
text: "Change the Template",
onClick: function (e) {
const currentTemplate = tooltip.option("contentTemplate");
