ngx-smart-popover

Simple popover control for your angular (v8+) applications using bootstrap4 with smart reflection logic when overflowing the viewport. This is a continuation of ngx-popover (https://github.com/pleerock/ngx-popover). If you want to use it without bootstrap - simply create corresponding css classes.

See a quick demo - https://lsqlabs.github.io/ngx-smart-popover/

Installation

1. Install npm module:

   npm install ngx-smart-popover --save

2. If you are using system.js you may want to add this into map and package config:

   {
       "map": {
           "ngx-smart-popover": "node_modules/ngx-smart-popover"
       },
       "packages": {
           "ngx-smart-popover": { "main": "index.js", "defaultExtension": "js" }
       }
   }

Usage

Import PopoverModule in your app and start using a component:

<div popover="content to be shown in the popover"
     popoverTitle="Popover header"
     popoverPlacement="top"
     [popoverOnHover]="false"
     [popoverCloseOnClickOutside]="true"
     [popoverCloseOnMouseOutside]="false"
     [popoverDisabled]="false"
     [popoverAnimation]="true"
     [popoverDismissTimeout]="1000">
    element on which this popover is applied.
</div>

Example of usage with dynamic html content:

<popover-content #myPopover 
                title="Popover title" 
                placement="left"
                [animation]="true" 
                [closeOnClickOutside]="true" >
    <b>Very</b> <span style="color: #C21F39">Dynamic</span> <span style="color: #00b3ee">Reusable</span>
    <b><i><span style="color: #ffc520">Popover With</span></i></b> <small>Html support</small>.
</popover-content>

<button [popover]="myPopover">element on which this popover is applied.</button>

Styles

Import the bootstrap styles as a starting point. This module ships with both a CSS file as well as an SCSS file. In order to be able to use the diagonal positions (top-right, bottom-right, top-left, bottom-left) you must import one of these two stylesheets. It will ensure that your arrow is centered via CSS (bootstrap handles this in Javascript). The SASS file is provided in case you have overwritten any of the bootstrap SASS variables and want to compile with the non-default values.

Sample

import {Component} from "@angular/core";
import {PopoverModule} from "ngx-smart-popover";

@Component({
    selector: "app",
    template: `
<div class="container">

    <!-- regular popover -->
    <p>
        It is a long established <span popover="Hello fact!" popoverTitle="Fact #1"><b>click this fact</b></span> that a reader will be distracted by the readable content of a page when looking at its layout.
        The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.
        <span popover="many, but not all" popoverPlacement="left"><b>Many desktop</b></span> publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy.
        <span popover="various, but not all" popoverPlacement="right"><b>Various versions</b></span> have evolved over the years, sometimes by accident, <span popover="another hint" popoverPlacement="top"><b>sometimes on purpose</b></span> (injected humour and the like)
    </p>

    <br/>
    <button popover="Hello popover. Now click outside." [popoverCloseOnClickOutside]="true">
        click to open popover that will be closed when you click outside of it.
