Radial menu in Angular Speed dial component

27 Sep 20235 minutes to read

The Angular Speed Dial action items can be displayed in a circular patter like a radial menu by setting mode property. You can customize the direction, startAngle, endAngle and offset by setting radialSettings property.

Radial menu direction

You can open the action items in either clockwise or anticlockwise by setting direction property. The default value is Auto where the action items are displayed based on the position property of the Speed Dial.

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    template: `<!-- To Render SpeedDial component. -->
    <button ejs-speeddial id="speeddial" openIconCss='e-icons e-edit' closeIconCss='e-icons e-close' target='#targetElement' [items]='items' mode= 'Radial' [radialSettings]= 'radialSettings'></button>`
})

export class AppComponent {
  public items: SpeedDialItemModel[] = [
    { iconCss: 'e-icons e-cut' },
    { iconCss: 'e-icons e-copy' },
    { iconCss: 'e-icons e-paste' },
    { iconCss: 'e-icons e-edit' },
    { iconCss: 'e-icons e-save' }
  ];

  public radialSettings: RadialSettingsModel = { direction: 'AntiClockwise' };
}

Radial menu start and end angle

You can modify the start and end angle of action items by setting startAngle and endAngle properties. If the angle is not defined, the action items are displayed based on the position property of the Speed Dial.

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    template: `<!-- To Render SpeedDial component. -->
    <button ejs-speeddial id="speeddial" openIconCss='e-icons e-edit' closeIconCss='e-icons e-close' target='#targetElement' [items]='items' mode= 'Radial' position='MiddleCenter' [radialSettings]= 'radialSettings'></button>`
})

export class AppComponent {
  public items: SpeedDialItemModel[] = [
    { iconCss: 'e-icons e-cut' },
    { iconCss: 'e-icons e-copy' },
    { iconCss: 'e-icons e-paste' },
    { iconCss: 'e-icons e-edit' },
    { iconCss: 'e-icons e-save' }
  ];

    public radialSettings: RadialSettingsModel = { direction: 'AntiClockwise', startAngle: 180, endAngle: 360 };
}

Offset

You can modify the offset distance between action items and Speed Dial button using offset property.

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    template: `<!-- To Render SpeedDial component. -->
    <button ejs-speeddial id="speeddial" openIconCss='e-icons e-edit' closeIconCss='e-icons e-close' target='#targetElement' [items]='items' mode= 'Radial' [radialSettings]= 'radialSettings'></button>`
})

export class AppComponent {
  public items: SpeedDialItemModel[] = [
    { iconCss: 'e-icons e-cut' },
    { iconCss: 'e-icons e-copy' },
    { iconCss: 'e-icons e-paste' }
  ];

  public radialSettings: RadialSettingsModel = { offset: '80px' };
}

Below example demonstrates the radial menu settings of the Speed Dial.

app.component.ts

import { Component } from '@angular/core';
import { RadialSettingsModel, SpeedDialItemModel } from '@syncfusion/ej2-angular-buttons';
@Component({
    selector: 'app-root',
    template: `<div id="targetElement" style="position:relative;min-height:350px;border:1px solid;"><div>
    <!-- To Render SpeedDial component. -->
    <button ejs-speeddial id="speeddial" openIconCss='e-icons e-edit' closeIconCss='e-icons e-close' target='#targetElement' [items]='items' mode= 'Radial' position= 'MiddleRight' [radialSettings]= 'radialSettings'></button>`
})

export class AppComponent {
  public items: SpeedDialItemModel[] = [
    { iconCss: 'e-icons e-cut' },
    { iconCss: 'e-icons e-copy' },
    { iconCss: 'e-icons e-paste' },
    { iconCss: 'e-icons e-edit' },
    { iconCss: 'e-icons e-save' }
  ];

  public radialSettings: RadialSettingsModel = { offset: '80px', direction: 'AntiClockwise', startAngle: 90, endAngle: 270 };

}
