Accordion group allowing only one section expanded at a time, automatically closing others. Use single-expand behavior when content sections are mutually exclusive or when you want to maintain compact vertical space by limiting expanded content to one section.

Accordion with custom CSS transitions for enhanced visual feedback during state changes. Use animated accordions to provide smoother, more polished interactions, particularly in content-heavy interfaces where transitions help users track what changed.

Accordion with custom icon button that changes based on state. Use custom icons to provide more semantic indicators (e.g., plus/minus for add/remove patterns, chevron for expand/collapse).

<nve-accordion id="custom-icon-button-accordion">
  <nve-icon-button slot="icon-button" icon-name="add" size="sm" container="flat"></nve-icon-button>
  <nve-accordion-header>
    <h2 nve-text="heading xs medium" slot="prefix">Additional Resources</h2>
  </nve-accordion-header>
  <nve-accordion-content
    >Adjust workspace preferences and project configurations to customize your experience.</nve-accordion-content
  >
</nve-accordion>
<script type="module">
  const accordion = document.querySelector("#custom-icon-button-accordion");
  const accordionHeader = accordion.querySelector("nve-accordion-header");
  const iconButton = accordion.querySelector("nve-icon-button");
  accordionHeader.addEventListener("click", () => toggle());
  iconButton.addEventListener("click", () => toggle());
  function toggle() {
    accordion.expanded = !accordion.expanded;
    iconButton.iconName = accordion.expanded ? "minus" : "add";
  }
</script>

Accordion with action buttons in header for quick operations without expanding. Perfect for list items where users need both to view details and perform actions like edit, delete, or add, keeping common actions immediately accessible.
