Integrate Third-Party Angular Components
This help topic describes how to integrate a third-party Angular component into a standalone survey and Survey Creator. As an example, we will integrate the Angular Color component. To install it, run the following command:
npm install ngx-color --save
You also need to list Angular Color modules within app.module.ts
:
// app.module.ts
import { ColorSketchModule } from "ngx-color/sketch";
import { ColorSliderModule } from "ngx-color/slider";
import { ColorCompactModule } from "ngx-color/compact";
@NgModule({
declarations: [ ... ],
imports: [
// ...
ColorSketchModule,
ColorSliderModule,
ColorCompactModule
],
// ...
})
export class AppModule { }
The following live example illustrates Survey Creator with an integrated Angular Color component:
Create a Model
To integrate a third-party component, you need to configure a custom question type for it. All question types in SurveyJS demand a model. To create it, add a custom class (QuestionColorPickerModel
in the code below) that extends the Question
class and inherits all its properties and methods. Override the getType()
method with an implementation that returns the name of your custom question type. If the model requires custom properties, declare them as getter + setter pairs. In the following code, the model includes two such properties: colorPickerType
and disableAlpha
.
import { Question } from "survey-core";
const CUSTOM_TYPE = "color-picker";
export class QuestionColorPickerModel extends Question {
getType() {
return CUSTOM_TYPE;
}
get colorPickerType() {
return this.getPropertyValue("colorPickerType");
}
set colorPickerType(val) {
this.setPropertyValue("colorPickerType", val);
}
get disableAlpha() {
return this.getPropertyValue("disableAlpha");
}
set disableAlpha(val) {
this.setPropertyValue("disableAlpha", val);
}
}
Register the created model in the ElementFactory
under the name returned by the getType()
method:
import { ElementFactory } from "survey-core";
const CUSTOM_TYPE = "color-picker";
ElementFactory.Instance.registerElement(
CUSTOM_TYPE,
(name) => {
return new QuestionColorPickerModel(name);
}
);
Configure JSON Serialization
Our model exists only in JavaScript code, but SurveyJS works with JSON objects. You need to configure how your model should be serialized into JSON. To do this, call the addClass(name, propMeta[], constructor, baseClassName)
method on the Serializer
object. This method accepts the following arguments:
name
A string value that you returned from the model'sgetType()
method. This property is used to associate the JSON object with the model's JavaScript class.propMeta[]
An array of objects used to serialize custom model properties into JSON. This array must include all custom model properties. Our model contains two custom properties (colorPickerType
anddisableAlpha
), and the code below configures their serialization.constructor
A function that returns an instance of the model's JavaScript class (QuestionColorPickerModel
) associated with the JSON object.baseClassName
The name of a class that the custom class extends ("question"
).
import { ..., Serializer } from "survey-core";
const CUSTOM_TYPE = "color-picker";
Serializer.addClass(
CUSTOM_TYPE,
[{
name: "colorPickerType",
default: "Slider",
choices: ["Slider", "Sketch", "Compact"],
category: "general",
visibleIndex: 2 // Place after the Name and Title
}, {
name: "disableAlpha:boolean",
dependsOn: "colorPickerType",
visibleIf: function (obj) {
return obj.colorPickerType === "Sketch";
},
category: "general",
visibleIndex: 3 // Place after the Name, Title, and Color Picker Type
}],
function () {
return new QuestionColorPickerModel("");
},
"question"
);
Render the Third-Party Component
Implement a custom Angular component that renders the desired UI elements. This component's class should extend the QuestionAngular
generic class that accepts a question model (QuestionColorPickerModel
in our case). Model properties are available through the context variable this
. Your custom component can include additional members. For example, ColorPickerComponent
in the code below contains a handleChange
function that sets the selected color as a question value.
import { Component } from "@angular/core";
import { QuestionAngular } from "survey-angular-ui";
import { ColorEvent } from 'ngx-color';
@Component({
selector: "color-picker",
templateUrl: "./color-picker.component.html",
styleUrls: [ "./color-picker.component.css" ]
})
export class ColorPickerComponent extends QuestionAngular<QuestionColorPickerModel> {
handleChange($event: ColorEvent) {
this.model.value = $event.color.hex;
}
}
// A custom question model configured earlier
export class QuestionColorPickerModel extends Question {
// ...
}
The component's template should render different color picker elements based upon the colorPickerType
property value:
<ng-container *ngIf="model.colorPickerType === 'Sketch'">
<color-sketch [disableAlpha]="model.disableAlpha" (onChange)="handleChange($event)" [color]="model.value || '#fff'"></color-sketch>
</ng-container>
<ng-container *ngIf="model.colorPickerType === 'Slider'">
<color-slider (onChange)="handleChange($event)" [color]="model.value || '#fff'"></color-slider>
</ng-container>
<ng-container *ngIf="model.colorPickerType === 'Compact'">
<color-compact (onChange)="handleChange($event)" [color]="model.value || '#fff'"></color-compact>
</ng-container>
Register your custom component (ColorPickerComponent
) as a component that renders a custom question type (color-picker-question
):
import { ..., AngularComponentFactory } from "survey-angular-ui";
AngularComponentFactory.Instance.registerComponent(CUSTOM_TYPE + "-question", ColorPickerComponent);
Import your custom component into AppComponent
as shown in the code below. Otherwise, the component may be removed from the production build by tree shaking.
// app.component.ts
import { Component } from '@angular/core';
import { ColorPickerComponent } from './color-picker/color-picker.component';
@Component({
// ...
})
export class AppComponent {
static declaration = [ColorPickerComponent];
}

Specify Captions
Survey Creator generates captions for your custom question type and its properties automatically. If you need to change them, use the localization engine:
import { editorLocalization } from "survey-creator-core";
const CUSTOM_TYPE = "color-picker";
const locale = editorLocalization.getLocale("");
locale.qt[CUSTOM_TYPE] = "Color Picker";
locale.pe.colorPickerType = "Color picker type";
locale.pe.disableAlpha = "Disable alpha channel";

Add an Icon
Each question type has an icon that is displayed next to the type name in the Toolbox and the Add Question menu. The following code shows how to register an SVG icon for your custom question type:
import { ..., SvgRegistry } from "survey-core"
const CUSTOM_TYPE = "color-picker";
SvgRegistry.registerIconFromSvg(
CUSTOM_TYPE,
'<svg viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg"><path d="..." /></svg>'
);
Alternatively, you can use one of built-in SurveyJS icons. The code below shows how to use the Text icon:
import { ..., settings } from "survey-core";
const CUSTOM_TYPE = "color-picker";
settings.customIcons["icon-" + CUSTOM_TYPE] = "icon-text";

Use the Custom Component as an Editor in the Property Grid
The Property Grid is built upon a regular survey and can be customized using the same techniques. It means that if you integrate a third-party component into a survey, you can integrate it into the Property Grid with little effort. For example, the following code shows how to register the Color Picker configured in this tutorial as an editor for the properties of the "color"
type:
// color-picker.component.ts
import { ..., PropertyGridEditorCollection } from "survey-creator-core";
const CUSTOM_TYPE = "color-picker";
PropertyGridEditorCollection.register({
fit: function (prop) {
return prop.type === "color";
},
getJSON: function () {
return {
type: CUSTOM_TYPE,
colorPickerType: "Compact"
};
}
});
To try the functionality, you can add a custom property of the "color"
type to the survey. The code below adds a custom backgroundColor
property. When users change its value, they change the --background
CSS variable. The onActiveTabChanged
event handler reapplies the selected background color when users switch to the Designer or Preview tab.
// survey-creator.component.ts
import { Component, OnInit } from "@angular/core";
import { SurveyCreatorModel } from "survey-creator-core";
import { Serializer, SurveyModel } from "survey-core";
function applyBackground(color) {
setTimeout(() => {
const surveyEl = document.getElementsByClassName("sd-root-modern")[0] as HTMLElement;
if (!!surveyEl) {
surveyEl.style.setProperty("--background", color);
}
}, 50);
};
function handleActiveTabChange(sender, options) {
if (options.tabName === "test" || options.tabName === "designer") {
applyBackground(sender.survey.backgroundColor);
}
};
const creatorOptions = {
showLogicTab: true
};
@Component({
selector: "survey-creator-component",
templateUrl: "./survey-creator.component.html",
styleUrls: ["./survey-creator.component.css"]
})
export class SurveyCreatorComponent implements OnInit {
surveyCreatorModel!: SurveyCreatorModel;
ngOnInit() {
const creator = new SurveyCreatorModel(creatorOptions);
Serializer.addProperty("survey", {
name: "backgroundColor",
displayName: "Background color",
type: "color",
category: "general",
visibleIndex: 3,
onSetValue: (survey: SurveyModel, value) => {
survey.setPropertyValue("backgroundColor", value);
applyBackground(value);
}
});
creator.onActiveTabChanged.add(handleActiveTabChange);
this.surveyCreatorModel = creator;
}
}
You might want to use a third-party component only as a property editor, without allowing survey editors to use it in questions. In this case, you need to hide the component from the Toolbox and the Add Question menu. To do this, pass false
as a third argument to the ElementFactory.Instance.registerElement
method when you register a freshly created model:
import { ElementFactory } from "survey-core";
const CUSTOM_TYPE = "color-picker";
ElementFactory.Instance.registerElement(
CUSTOM_TYPE,
(name) => {
return new QuestionColorPickerModel(name);
},
false
);
