Item configuration in Angular Toolbar component

10 Jan 202314 minutes to read

The Toolbar can be rendered by defining an array of items. Items can be constructed with the following built-in command types or item template.

Button

Button is the default command type, and it can be rendered by using the text property.
Properties of the button command type:

Property Description
text The text to be displayed for button.
id The ID of the button to be rendered. If the ID is not given, auto ID is generated.
prefixIcon Defines the class used to specify an icon for the button. The icon is positioned before the text if text is available or the icon alone button is rendered.
suffixIcon Defines the class used to specify an icon for the button. The icon is positioned after the text if text is available. If both prefixIcon and suffixIcon are specified, only prefixIcon is considered.
width Used to set the width of the button.
align Specifies the location for aligning Toolbar items.

Separator

The Separator type adds a vertical separation between the Toolbar’s single/multiple commands.

import { Component, ViewChild } from '@angular/core';
import { ToolbarComponent } from '@syncfusion/ej2-angular-navigations';

@Component({
    selector: 'app-container',
    template: `
        <ejs-toolbar>
          <e-items>
             <e-item text='Cut'></e-item>
             <e-item text='Copy'></e-item>
             <e-item type='Separator'></e-item>
             <e-item text='Paste'></e-item>
             <e-item type='Separator'></e-item>
             <e-item text='Undo'></e-item>
             <e-item text='Redo'></e-item>
          </e-items>
        </ejs-toolbar>
        `
})

export class AppComponent {

}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ToolbarModule } from '@syncfusion/ej2-angular-navigations';
import { TooltipModule } from '@syncfusion/ej2-angular-popups';
import { AppComponent } from './app.component';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, ToolbarModule, TooltipModule
    ],
    declarations: [AppComponent ],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

If Separator is added as first or last item, it is not visible.

Input

The Input type is only applicable for adding template elements when the template property is defined as an object.
Input type creates an input element internally that acts as the container for Syncfusion input based components.

NumericTextBox

  • The NumericTextBox component can be included by importing the NumericTextBox module from ej2-inputs.

  • Initialize the NumericTextBox in template property, in which the Toolbar item type set as Input.

  • Related NumericTextBox component properties are also can be configured like as below.

new NumericTextBox( { format: 'c2' }))
  • The DropDownList component can be included by importing the DropDownList module from ej2-dropdowns.

  • Initialize the DropDownList in template property, in which the Toolbar item type set as Input.

  • Related DropDownList component properties are also can be configured like as below.

new DropDownList({ width:100 })

CheckBox

  • The CheckBox component can be included by importing the CheckBox module from ej2-buttons.

  • Initialize the CheckBox in template property, in which the Toolbar item type set as Input.

  • Related CheckBox component properties are also can be configured like as below.

new CheckBox({ label: 'Checkbox', checked: true })

RadioButton

  • The RadioButton component can be included by importing the RadioButton module from ej2-buttons.

  • Initialize the RadioButton in template property, in which the Toolbar item type set as Input.

  • Related RadioButton component properties are also can be configured like as below.

new RadioButton({ label: 'Radio', name: 'default', checked: true })

Above steps applicable for all ‘Syncfusion’ input based components.

import { Component, ViewChild } from '@angular/core';
import { ToolbarComponent } from '@syncfusion/ej2-angular-navigations';
import { NumericTextBox} from '@syncfusion/ej2-inputs';
import { DropDownList} from '@syncfusion/ej2-dropdowns';
import { CheckBox, RadioButton  } from '@syncfusion/ej2-buttons';

@Component({
    selector: 'app-container',
    template: `
        <ejs-toolbar (created)="onCreate($event)">
          <e-items>
             <e-item text='Cut'></e-item>
             <e-item text='Copy'></e-item>
             <e-item type='Separator'></e-item>
             <e-item text='Undo'></e-item>
             <e-item text='Redo'></e-item>
             <e-item template=' <input id="numeric" type="text" />' type = 'Input'></e-item>
             <e-item template='<input type="text" tabindex="1" id="ddlelement" />' type = 'Input'></e-item>
             <e-item template='<input id="chkelement" type="checkbox"/>' type = 'Input'></e-item>
             <e-item template='<input id="rdelement" type="radio"/>' type = 'Input'></e-item>
          </e-items>
        </ejs-toolbar>
        `
})

export class AppComponent {
    @ViewChild('element') element;
    public data: string[] = ['Badminton', 'Basketball', 'Cricket', 'Golf', 'Hockey', 'Rugby'];
    public templateEle: any = new NumericTextBox({ format: 'c2', value: 1, width: 150 });
    public templateDropdown: any = new DropDownList({ dataSource: this.data, width: 120, index: 2 });
    public templateCheckbox: any = new CheckBox({ label: 'Checkbox', checked: true });
    public templateRadiobutton: any = new RadioButton({ label: 'Radio', name: 'default', checked: true });
    public onCreate (e: any) {
      this.templateCheckbox.appendTo('#chkelement');
      this.templateDropdown.appendTo('#ddlelement');
      this.templateEle.appendTo('#numeric');
      this.templateRadiobutton.appendTo('#rdelement');
    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ToolbarModule } from '@syncfusion/ej2-angular-navigations';
import { TooltipModule } from '@syncfusion/ej2-angular-popups';
import { AppComponent } from './app.component';

/**

@NgModule({
    imports: [
        BrowserModule, ToolbarModule, TooltipModule
    ],
    declarations: [AppComponent ],
    bootstrap: [AppComponent]
})
export class AppModule { }

import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Enabling tab key navigation in Toolbar

The tabIndex property of a Toolbar item is used to enable tab key navigation for the item. By default, the user can switch between items using the arrow keys, but the tabIndex property allows you to switch between items using the Tab and Shift+Tab keys as well.

To use the tabIndex property, you need to set it for each Toolbar item that you want to enable tab key navigation. The tabIndex property should be set to a positive integer value. A value of 0 or a negative value will disable tab key navigation for the item.

For example, to enable tab key navigation for two Toolbar items, you can use the following code:

import { Component, ViewChild } from '@angular/core';
import { ToolbarComponent } from '@syncfusion/ej2-angular-navigations';

@Component({
    selector: 'app-container',
    template: `
        <ejs-toolbar>
          <e-items>
             <e-item text='item1' tabIndex=1></e-item>
             <e-item text='item2' tabIndex=2></e-item>
          </e-items>
        </ejs-toolbar>
        `
})

export class AppComponent {

}

With the above code, the user can switch between the two Toolbar items using the Tab and Shift+Tab keys, in addition to using the arrow keys. The items will be navigated in the order specified by the tabIndex values.

If you set the tabIndex value to 0 for all Toolbar items, tab key navigation will be based on the element order rather than the tabIndex values. For example:

import { Component, ViewChild } from '@angular/core';
import { ToolbarComponent } from '@syncfusion/ej2-angular-navigations';

@Component({
    selector: 'app-container',
    template: `
        <ejs-toolbar>
          <e-items>
             <e-item text='item1' tabIndex=0></e-item>
             <e-item text='item2' tabIndex=0></e-item>
          </e-items>
        </ejs-toolbar>
        `
})

export class AppComponent {

}

In this case, the user can switch between the two Toolbar items using the Tab and Shift+Tab keys, and the items will be navigated in the order in which they appear in the DOM.

Example:

Here is an example of how you can use the tabIndex property to enable tab key navigation for a Toolbar component:

import { Component, ViewChild } from '@angular/core';
import { ToolbarComponent } from '@syncfusion/ej2-angular-navigations';

@Component({
    selector: 'app-container',
    template: `
        <ejs-toolbar>
          <e-items>
             <e-item text='Cut' tabIndex=0></e-item>
             <e-item text='Copy' tabIndex=0></e-item>
             <e-item type='Separator'></e-item>
             <e-item text='Paste' tabIndex=0></e-item>
             <e-item type='Separator'></e-item>
             <e-item text='Undo' tabIndex=0></e-item>
             <e-item text='Redo' tabIndex=0></e-item>
          </e-items>
        </ejs-toolbar>
        `
})

export class AppComponent {

}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ToolbarModule } from '@syncfusion/ej2-angular-navigations';
import { TooltipModule } from '@syncfusion/ej2-angular-popups';
import { AppComponent } from './app.component';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, ToolbarModule, TooltipModule
    ],
    declarations: [AppComponent ],
    bootstrap: [AppComponent]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

With the above code, the user can switch between the Toolbar items using the Tab and Shift+Tab keys, and the items will be navigated based on the element order.
