About

Popovers hide or show content as a result of user interaction, such as clicking, hovering, or focusing. When opened, the content remains connected to the element that triggered it.

Getting Started

Let's start by installing wes-popover as a dependency of your project with npm.

npm i @salesforce-ux/wes-popover

After installation, all the distributables for the wes-popover are found under @salesforce-ux/wes-popover/dist/ folder.

File Name	Description
`popover.css`	The CSS file specific to `wes-popover` only.

`wes-popover` Integration

For the sake of understanding, we have categorized the development environment into LWC and Non LWC application. If you are using the Salesforce Experience Cloud platform, WES is supported through an Unlocked Package, see the Confluence page for the WES Unlocked Package.

This Guide covers the integration approach for these two types of application.

Dependency Inclusion

wes-styling-hooks is a styling dependency for wes-popover. Hence, this needs to be embedded into the root of the web app in order to make the wes-popover render properly.

<html>
  <head>
    <link rel="stylesheet" href="/node_modules/@salesforce-ux/wes-styling-hooks/dist/hooks.custom-props.css">
    <!-- Your application's other stylesheets go below -->
    <link rel="stylesheet" href="...">
  </head>
  <body>
    <!-- Your application -->
  </body>
</html>

There are also other ways wes-styling-hooks can be embedded. Please checkout the wes-styling-hooks Integration Guide to learn more.

Component CSS Import

/* myComponent.css */
@import '@salesforce-ux/wes-popover/dist/popover.css';

HTML Decoration

After that,the HTML of your LWC component template needs to be decorated to have all the named part attributes as per the component's specification. Below is a reference to the component's structure.

<wes-popover placement="below-center" depth="2">
  <div part="source" aria-haspopup="true">
    <!-- This is the placeholder to configure popover trigger element -->
  </div>
  <div part="popup" exportparts="backdrop, frame" role="dialog" aria-label="popup" closed>
    <div part="frame" role="none">
      <wes-button id="dismissible" variant="tertiary" size="default"
        ><wes-icon slot="end" symbol="close"></wes-icon
      ></wes-button>
      <div part="popup-container">
        <!-- This is the placeholder to configure popover container -->
      </div>
    </div>
  </div>
</wes-popover>
