ngx-popperjs

ngx-popperjs is an angular wrapper for the Popper.js library.

Note that I also updated everything to use Popper 2 (v 2.4.4 in v 9.0.0)

VERY IMPORTANT READ THIS

I'm moving this to the top because it appears that people don't get to reading it in the contribute section. FOR THIS LIBRARY PLEASE USE ISSUES ONLY FOR BUG REPORTING. DON'T OPEN ISSUES SUCH AS "I need upgrade for Angular 1745646456" especially if Angular 1745646456 was released a few days ago. I guarantee that I manage the updates AS SOON AS POSSIBLE. But as you understand this is not a paying job, so you can't get Angular 1745646456 the day it gets released. ISSUES NOT RESPECTING THIS WILL BE DELETED IMMEDIATELY WITHOUT ANY RESPONSE. Thank you.

The goal of this library is to take Mr Frankel's ngx-popper and update the compatibility for more recent versions of Angular. Since the old library is compatible with Angular 7 and earlier, I started with Angular 8. If you need to work with an older version of Angular (5 to 7), please refer to Mr Frankel's ngx-popper.

Premise, new in v 15.2.0: popperLoose

Since many complained about using the NgxPopperjsPlacements enum, I added a version of the popper directive which accepts a plain string as placement! Now you can use it with all the options of the classic popper, but you'll have to use:

popperLoose instead of popper

and

popperLoosePlacement instead of popperPlacement

Installation

node and npm are required to run this package.

1. Use npm/yarn to install the package:

$ npm install @popperjs/core ngx-popperjs --save

Or

 $ yarn add @popperjs/core --save
 $ yarn add ngx-popperjs --save 

2. You simply add into your module NgxPopperjsModule:

import {NgxPopperjsModule} from 'ngx-popperjs';

@NgModule({
 // ...
 imports: [
   // ...
   NgxPopperjsModule
 ]
})

Optionally you can include in your styles.css / styles.css one of the prebuilt themes:

• @import node_modules/ngx-popperjs/css/theme-dark.css

• @import node_modules/css/theme-white.css

• @use ngx-popperjs/scss/theme as popperBaseTheme

• @use ngx-popperjs/scss/theme-dark as popperDarkTheme

• @use ngx-popperjs/scss/theme-white popperWhiteTheme

or easily create your own theme using the @mixin:

@use "ngx-popperjs/scss/theme" as popperBaseTheme;

body {
    @include popperjs.ngx-popperjs-theme($background-color, $text-color, $max-width, $z-index);
}

3. Add to view:

 <popper-content #popper1Content>
     <p class="bold">Popper on bottom</p>
 </popper-content>
 <div [popper]="popper1Content"
      [popperShowOnStart]="true"
      [popperTrigger]="'click'"
      [popperHideOnClickOutside]="true"
      [popperHideOnScroll]="true"
      [popperPlacement]="'bottom'">
     <p class="bold">Hey!</p>
     <p class="thin">Choose where to put your popper!</p>         
 </div>

4. As text:

     <div popper="As text"
          [popperTrigger]="'hover'"
          [popperPlacement]="'bottom'"
          (popperOnShown)="onShown($event)">
       <p class="bold">Pop</p>
       <p class="thin">on the bottom</p>
     </div>

     <div popper="{{someTextProperty}}"
          [popperTrigger]="'hover'"
          [popperPlacement]="'bottom'"
          [popperStyles]="{'background-color: 'blue''}",
          (popperOnShown)="onShown($event)">
       <p class="bold">Pop</p>
       <p class="thin">on the bottom</p>
     </div>

5. Position fixed, breaking overflow:

     <div popper="As text"
          [popperTrigger]="'hover'"
          [popperPlacement]="'bottom'"
          [popperPositionFixed]="true"
          (popperOnShown)="onShown($event)">
     </div>

6. Specific target:

<div class="example">
     <div #popperTargetElement></div>
     <div popper="As text"
          popperTrigger="hover"
          popperPlacement="bottom"
          [popperTarget]="popperTargetElement.nativeElement"
          (popperOnShown)="onShown($event)">
     </div>

7. hide/show programmatically:

 <div [popper]="tooltipcontent"
      popperTrigger="hover"
      popperPlacement="bottom"
      [popperApplyClass]="'popperSpecialStyle'">
      <p class="bold">Pop</p>
      <p class="thin">on the bottom</p>
    </div>
    <popper-content #tooltipcontent>
      <div>
        <p>This is a tooltip with text</p>
        <span (click)="tooltipcontent.hide()">Close</span>
      </div>
    </popper-content>
