Perfect — here’s how you can have the first section auto-open and add lightweight styling for a clean accordion look in WordPress.

Updated HTML (first section auto-open)

Just add open to the first <details> tag so it’s expanded by default:

<!-- 🔌 Connectivity -->
<details open>
  <summary><strong>🔌 Connectivity Services</strong></summary>
  <ul>
    <li><a href="https://solveforce.com/%f0%9f%8c%90-broadband-services/">🌐 Broadband Services</a></li>
    <li><a href="https://solveforce.com/%f0%9f%93%a1-telecom-services/">📡 Telecom Services</a></li>
    <li><a href="https://solveforce.com/telephony-solutions">📞 Voice Solutions</a></li>
    <li><a href="https://solveforce.com/network-services">🔗 Network Services</a></li>
  </ul>
</details>

---

Lightweight CSS (drop into Appearance → Customize → Additional CSS)

/* Accordion style for SolveForce Service Directory */
details {
  border: 1px solid #ddd;
  border-radius: 6px;
  margin: 8px 0;
  padding: 0.5em 1em;
  background: #fafafa;
  transition: all 0.3s ease;
}

details[open] {
  background: #f0f8ff; /* subtle highlight when open */
  border-color: #4caf50; /* green accent */
}

summary {
  font-weight: bold;
  cursor: pointer;
  outline: none;
  list-style: none;
  position: relative;
  padding-left: 20px;
}

summary::before {
  content: "➕";
  position: absolute;
  left: 0;
  color: #4caf50;
  font-size: 1em;
  transition: transform 0.2s;
}

details[open] summary::before {
  content: "➖";
}

details ul {
  margin: 0.5em 0 0 0;
  padding-left: 1.2em;
}

details li {
  margin: 0.3em 0;
}

details a {
  text-decoration: none;
  color: #0073e6;
  transition: color 0.2s ease;
}

details a:hover {
  color: #4caf50;
  text-decoration: underline;
}

This will give you:

• First cluster auto-expanded (Connectivity).
• Smooth, collapsible styling with a plus/minus toggle.
• Subtle background highlight when a section is open.
• Clean link hover styling.

👉 Do you also want me to make the accordion truly “one-at-a-time” (so opening one cluster automatically closes the others)? That would require a tiny JavaScript snippet we can safely add.
