### Common Patterns & Recipes

Copy-paste solutions for the patterns that show up in every admin dashboard. Each recipe assumes you’ve followed Getting Started and have a working AdminLTE page to build on.

##### A multi-level sidebar with icons, badges, and headers

The demo dashboards use this exact pattern. Group sections with `.nav-header`, indicate item depth with nested `.nav-treeview` lists, and use `.navbar-badge` for counts.

    <aside class="app-sidebar bg-body-secondary shadow" data-bs-theme="dark">
      <div class="sidebar-brand">
        <a href="/" class="brand-link">
          <span class="brand-text fw-light">My Dashboard</span>
        </a>
      </div>
      <div class="sidebar-wrapper">
        <nav class="mt-2">
          <ul class="nav sidebar-menu flex-column" data-lte-toggle="treeview" role="menu">

            <li class="nav-header">MAIN</li>
            <li class="nav-item">
              <a href="/" class="nav-link active">
                <i class="nav-icon bi bi-speedometer"></i>
                <p>Dashboard</p>
              </a>
            </li>

            <li class="nav-item">
              <a href="#" class="nav-link">
                <i class="nav-icon bi bi-folder"></i>
                <p>
                  Projects
                  <span class="badge text-bg-info ms-2">12</span>
                  <i class="nav-arrow bi bi-chevron-right"></i>
                </p>
              </a>
              <ul class="nav nav-treeview">
                <li class="nav-item">
                  <a href="#" class="nav-link"><i class="nav-icon bi bi-circle"></i><p>Active</p></a>
                </li>
                <li class="nav-item">
                  <a href="#" class="nav-link"><i class="nav-icon bi bi-circle"></i><p>Archived</p></a>
                </li>
              </ul>
            </li>

            <li class="nav-header">REPORTS</li>
            <li class="nav-item">
              <a href="#" class="nav-link">
                <i class="nav-icon bi bi-bar-chart"></i>
                <p>Sales</p>
                <span class="badge text-bg-danger ms-auto">3</span>
              </a>
            </li>

          </ul>
        </nav>
      </div>
    </aside>

To mark the current page as active, server-render the `.active` class onto the matching `.nav-link`. For SPA frameworks, add it on route change.

##### Highlighting the active sidebar item from JavaScript

If you’re rendering the sidebar once and want client-side route highlighting:

    function setActiveSidebarItem(href) {
      document.querySelectorAll(".sidebar-menu .nav-link").forEach((el) => {
        el.classList.toggle("active", el.getAttribute("href") === href)
      })
    }

    // Call on route change
    setActiveSidebarItem(window.location.pathname)

##### Responsive data tables

Wrap a `<table>` in `.table-responsive` so it gets a horizontal scrollbar on narrow viewports instead of overflowing the card.

    <div class="card">
      <div class="card-header">
        <h3 class="card-title">Recent orders</h3>
      </div>
      <div class="card-body p-0">
        <div class="table-responsive">
          <table class="table table-striped align-middle mb-0">
            <thead>
              <tr>
                <th>#</th>
                <th>Customer</th>
                <th>Total</th>
                <th>Status</th>
                <th class="text-end">Actions</th>
              </tr>
            </thead>
            <tbody>
              <!-- rows -->
            </tbody>
          </table>
        </div>
      </div>
    </div>

For interactive sorting/filtering/pagination, use Tabulator — `tables/data.html` in the demo has a full example.

##### A user dropdown in the topbar

    <li class="nav-item dropdown user-menu">
      <a href="#" class="nav-link dropdown-toggle" data-bs-toggle="dropdown">
        <span class="d-none d-md-inline me-1">Jane Doe</span>
        <i class="bi bi-person-circle fs-5"></i>
      </a>
      <ul class="dropdown-menu dropdown-menu-end">
        <li>
          <a href="/profile" class="dropdown-item">
            <i class="bi bi-person me-2"></i>Profile
          </a>
        </li>
        <li>
          <a href="/settings" class="dropdown-item">
            <i class="bi bi-gear me-2"></i>Settings
          </a>
        </li>
        <li><hr class="dropdown-divider"></li>
        <li>
          <a href="/logout" class="dropdown-item text-danger">
            <i class="bi bi-box-arrow-right me-2"></i>Sign out
          </a>
        </li>
      </ul>
    </li>

Put this inside the `<ul class="navbar-nav ms-auto">` in `.app-header`.

##### A KPI card (small-box)

The bright-coloured stat boxes at the top of most dashboards:

    <div class="row g-3">
      <div class="col-lg-3 col-6">
        <div class="small-box text-bg-primary">
          <div class="inner">
            <h3>150</h3>
            <p>New orders</p>
          </div>
          <i class="bi bi-cart small-box-icon" aria-hidden="true"></i>
          <a href="#" class="small-box-footer link-light">
            More info <i class="bi bi-arrow-right"></i>
          </a>
        </div>
      </div>
      <!-- repeat 3 more times with different values + colours -->
    </div>

Swap `text-bg-primary` for `text-bg-success`, `text-bg-warning`, `text-bg-danger`, etc.

##### A breadcrumb + page-title row

This is the standard `.app-content-header` pattern used across every demo page:

    <div class="app-content-header">
      <div class="container-fluid">
        <div class="row">
          <div class="col-sm-6">
            <h3 class="mb-0">Page Title</h3>
          </div>
          <div class="col-sm-6">
            <ol class="breadcrumb float-sm-end">
              <li class="breadcrumb-item"><a href="/">Home</a></li>
              <li class="breadcrumb-item"><a href="/section">Section</a></li>
              <li class="breadcrumb-item active" aria-current="page">Current page</li>
            </ol>
          </div>
        </div>
      </div>
    </div>

##### A timeline

For activity feeds, audit logs, or roadmap views:

    <div class="timeline">
      <div>
        <i class="bi bi-envelope bg-info" aria-hidden="true"></i>
        <div class="timeline-item">
          <span class="time"><i class="bi bi-clock"></i> 12:05</span>
          <h3 class="timeline-header">
            <a href="#">Olivia</a> sent you a message
          </h3>
          <div class="timeline-body">
            Hey, can we review the Q4 numbers tomorrow at 10?
          </div>
          <div class="timeline-footer">
            <a class="btn btn-primary btn-sm">Read more</a>
          </div>
        </div>
      </div>
      <!-- repeat -->
    </div>

The timeline component lives in `_timeline.scss` and has variants. See `/UI/timeline.html` for the full set.

##### A direct-chat widget

The chat-style card used for live customer support, team chat, etc. Includes contact toggle and message bubbles.

    <div class="card direct-chat direct-chat-primary">
      <div class="card-header">
        <h3 class="card-title">Direct Chat</h3>
        <div class="card-tools">
          <span class="badge text-bg-primary">3 new</span>
          <button type="button" class="btn btn-tool" data-lte-toggle="chat-pane" title="Contacts">
            <i class="bi bi-people-fill"></i>
          </button>
        </div>
      </div>
      <div class="card-body">
        <div class="direct-chat-messages">
          <div class="direct-chat-msg">
            <div class="direct-chat-infos clearfix">
              <span class="direct-chat-name float-start">Olivia</span>
              <span class="direct-chat-timestamp float-end">12:05</span>
            </div>
            <img class="direct-chat-img" src="/avatars/olivia.jpg" alt="" />
            <div class="direct-chat-text">Hey, ready for the review?</div>
          </div>
          <div class="direct-chat-msg right">
            <div class="direct-chat-infos clearfix">
              <span class="direct-chat-name float-end">You</span>
              <span class="direct-chat-timestamp float-start">12:06</span>
            </div>
            <img class="direct-chat-img" src="/avatars/me.jpg" alt="" />
            <div class="direct-chat-text">Yes, on my way.</div>
          </div>
        </div>
        <div class="direct-chat-contacts">
          <!-- contacts list, shown when chat-pane toggled -->
        </div>
      </div>
      <div class="card-footer">
        <form>
          <div class="input-group">
            <input type="text" class="form-control" placeholder="Message…" />
            <button type="submit" class="btn btn-primary">
              <i class="bi bi-send"></i>
            </button>
          </div>
        </form>
      </div>
    </div>

For a full-page chat application, see `/pages/chat.html` in the demo.

##### Reacting to layout/sidebar changes

Listen for plugin events to coordinate with your own code — e.g., refit a chart when the sidebar collapses (so the chart re-measures its container width):

    let chart = /* your ApexCharts instance */

    document.addEventListener("collapse.lte.push-menu", () => {
      // wait for the transition to finish (~300ms by default)
      setTimeout(() => chart.updateOptions({}), 350)
    })

    document.addEventListener("open.lte.push-menu", () => {
      setTimeout(() => chart.updateOptions({}), 350)
    })

The same pattern works for Tabulator, FullCalendar, and any other library that reads its container width on init.

##### Loading content into a card via fetch

    <div class="card" id="users-card">
      <div class="card-header">
        <h3 class="card-title">Users</h3>
        <div class="card-tools">
          <span class="spinner-border spinner-border-sm text-secondary d-none" id="users-spinner" role="status"></span>
        </div>
      </div>
      <div class="card-body p-0">
        <div id="users-body" class="text-secondary p-3">Loading&hellip;</div>
      </div>
    </div>

    <script>
      const spinner = document.getElementById("users-spinner")
      const body = document.getElementById("users-body")

      spinner.classList.remove("d-none")
      fetch("/api/users")
        .then((r) => r.text())
        .then((html) => { body.innerHTML = html })
        .catch(() => { body.textContent = "Failed to load." })
        .finally(() => spinner.classList.add("d-none"))
    </script>

##### Confirming destructive actions before submission

Bootstrap modal + a tiny confirmation pattern:

    <button type="button" class="btn btn-danger" data-bs-toggle="modal" data-bs-target="#confirmDelete">
      Delete account
    </button>

    <div class="modal fade" id="confirmDelete" tabindex="-1">
      <div class="modal-dialog">
        <div class="modal-content">
          <div class="modal-header">
            <h5 class="modal-title">Delete account?</h5>
            <button type="button" class="btn-close" data-bs-dismiss="modal"></button>
          </div>
          <div class="modal-body">
            This permanently deletes your account and all associated data. This cannot be undone.
          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-outline-secondary" data-bs-dismiss="modal">Cancel</button>
            <form action="/account/delete" method="POST" class="d-inline">
              <button type="submit" class="btn btn-danger">Yes, delete it</button>
            </form>
          </div>
        </div>
      </div>
    </div>

The Color Mode, Accessibility, and the bundled JS handle Escape-to-close, focus trap, and keyboard navigation inside the modal automatically.
