Documentation

yui-contextmenu

A simple context menu component for Angular 9+.

Documentation is work in progress.

WARNING

  • This component is written with Angular 9, so it will not work with earlier versions of Angular
  • Internet Explorer is not supported.
  • No RTL support.
  • Partial keyboard support.
  • This is a simple component I implemented for my personal project, so I cannot guarantee you with frequent updates/bug fixes.
  • If you are looking for better/more professional solutions, please check out other open-source projects such as ngx-contextmenu or ngx-rightclick.

Installation

  • Install the following packages:
npm i @angular/cdk @discordelia/popup @discordelia/contextmenu
  • Add the following line to your global stylesheet file (styles.scss)
@import "~@angular/cdk/overlay-prebuilt.css";
  • Import YuiContextmenuModule in your app.module.ts file (or another module where you need it.)

Usage

Basic Usage

<yui-contextmenu [target]="targetElement" [trigger]="'contextmenu'">
    <yui-menu-item text="Export Data">
        <yui-menu-item text="Export as XML"></yui-menu-item>
        <yui-menu-item text="Export as JSON"></yui-menu-item>
        <yui-menu-item text="Export as CSV"></yui-menu-item>

    <yui-menu-item [divider]="true"></yui-menu-item>
    <yui-menu-item text="Close"></yui-menu-item>
</yui-contextmenu>

<button #targetElement>Context Menu Button</button>

yui-contextmenu accepts the following inputs.

target   : The target element that the context menu will be attached to.
trigger  : You can set it to 'contextmenu' or 'click' to set the trigger event. Default is set to 'contextmenu'.
menuClass: You can pass a string of css classes to help you style the menu.
  • Inside yui-contextmenu tag, you can define multiple yui-menu-item components.
  • Inside yui-menu-item tag, you can define multiple yui-menu-item components for a submenu.
  • If, for example, you passed 'export-menu' as menuClass input, you can then use the following code to help you style the menu.
yui-contextmenu-content.export-menu {
    /* Your style rules */
}

yui-menu-item accepts the following inputs and outputs.

disabled: boolean                   // Disable a menu item.
divider: boolean                    // Set a menu item as divider. When set to true, all other options are ignored.
event: MouseEvent                   // Set the triggering event. Only used when the target changes dynamically.
icon: string;                       // Icon class for menu item. For example, you can pass a font icon class such as 'fa fa-plus'. Ignored when iconTemplate option is set.
iconTemplate: TemplateRef<any>;     // Pass a template reference to show as menu item icon.
image: string;                      // Image url for menu item icon. Ignored when iconTemplate option is set.
select: EventEmitter<IMenuItem>;    // Called when a menu item is selected. 
text: string;                       // Menu item text. Ignored when textTemplate option is set.
textTemplate: TemplateRef<any>;     // Pass a template reference to show as menu item text.
toggleable: boolean;                // Pass true if you want to make the menu item toggleable.
toggled: boolean;                   // Set toggle status of menu item. This is a two-way binding. [(toggled)]
visible: boolean;                   // Set false to hide a menu item.

Dynamic HTML Targets

If you want to change the target dynamically, you need to take a few extra steps.

  • Create the following public instance fields.
public menuEvent: MouseEvent;
public menuTarget: HTMLElement;
  • Create the yui-contextmenu component. For example;
<yui-contextmenu [target]="menuTarget" [trigger]="menuEvent?.type" [event]="menuEvent">
    <yui-menu-item text="Menu Item I"></yui-menu-item>
    <yui-menu-item text="Menu Item II"></yui-menu-item>
</yui-contextmenu>
  • Create a method that will set the values of menuTarget and menuEvent
public createMenu(event: MouseEvent): void {
    this.menuEvent = event;
    this.menuTarget = (event.target as HTMLElement);
}
  • Finally, call this createMenu method from a suitable context.
<div (contextmenu)="createMenu($event)"></div>
<p (contextmenu)="createMenu($event)"></p>
<button (click)="createMenu($event)"></button>
