opc-header component 👋

A standardized web component based on Lit Element for Red Hat One Platform Header that uses Patternfly Breadcrumb and Links as button HTML component

Prerequisites

The opc-header component is partially dependent on the Patternfly library for breadcrumbs and links. So to avoid any missing styles, add the patternfly.css file before the component script tags.

Usage

Plain Header

 <opc-header heading="OPC Header"></opc-header>

Header with Breadcrumbs and Links

 <opc-header heading="OPC Header">
  <opc-header-breadcrumb slot="breadcrumb"></opc-header-breadcrumb>
  <opc-header-links slot="links"></opc-header-links>
 </opc-header>

For custom options,

• use the opcHeaderBreadcrumb setter function to set the header breadcrumb
• use the opcHeaderLinks setter function to set the header links

  const breadcrumbs = [
    {
      "name":"Section Home",
      "href":"#"
    },
    {
      "name":"Section Landing",
      "href":"#"
    }];

  const links = [
    {
      "name":"Link1",
      "href":"#",
      "icon":"fa-play-circle"
    },
    {
      "name":"Link2",
      "href":"#",
      "icon":"fa-question-circle"
    },
    {
      "name":"Link3",
      "href":"#",
      "icon":"fa-file"
    }];

  document.querySelector("opc-header-breadcrumb").opcHeaderBreadcrumb = breadcrumbs;
  document.querySelector("opc-header-links").opcHeaderLinks = links;

Header with color themes

 <opc-header heading="OPC Header" theme="dark">
  <opc-header-breadcrumb slot="breadcrumb"></opc-header-breadcrumb>
  <opc-header-links slot="links"></opc-header-links>
 </opc-header>
