What Makes It Super

Focus Management

Automatic focus trap keeps keyboard navigation inside the modal. Returns focus to trigger element on close.

<div data-az-component="super-modal"
     data-az-focus-trap="true"
     data-az-restore-focus="true">

Backdrop Options

Blur, dim, or custom backdrop effects. Click-outside-to-close with optional prevention for unsaved changes.

<div data-az-backdrop="blur"
     data-az-close-on-backdrop="true"
     data-az-prevent-close-dirty="true">

Flexible Sizing

Preset sizes (sm, md, lg, xl, full) or custom dimensions. Auto-scroll for content overflow with sticky headers.

<div data-az-size="lg"
     data-az-max-height="80vh"
     data-az-scrollable="true">

Animation Presets

Slide, fade, zoom, or custom keyframe animations. Configurable duration and easing curves.

<div data-az-animation="slide-up"
     data-az-duration="300"
     data-az-easing="ease-out">

Stacking Support

Multiple modals can stack with automatic z-index management. LIFO close order with Escape key.

<div data-az-stackable="true"
     data-az-stack-offset="20"
     data-az-close-on-escape="true">

HTMX Content Loading

Load modal content from server via HTMX. Show loading states and handle errors gracefully.

<div data-az-content-url="/modal/user/1"
     data-az-loading="skeleton"
     hx-get="/modal/user/1">

Trigger Patterns

Multiple ways to open modals—buttons, links, or programmatic triggers—all declaratively configured.

<!-- Button Trigger -->
<button data-az-modal-trigger="user-modal">
  Open Modal
</button>

<!-- Link Trigger with HTMX -->
<a href="/users/1/edit" 
   data-az-modal-trigger="edit-modal"
   data-az-modal-content="htmx">
  Edit User
</a>

<!-- Modal Definition -->
<div data-az-component="super-modal"
     data-az-modal-id="user-modal"
     data-az-size="lg"
     data-az-backdrop="blur"
     data-az-animation="slide-up"
     role="dialog"
     aria-modal="true"
     aria-labelledby="modal-title">
  
  <header data-az-modal-header="true">
    <h2 id="modal-title">User Details</h2>
    <button data-az-modal-close="true" aria-label="Close">×</button>
  </header>
  
  <div data-az-modal-body="true">
    <!-- Content -->
  </div>
  
  <footer data-az-modal-footer="true">
    <button data-az-modal-close="true">Cancel</button>
    <button data-az-modal-confirm="true">Save</button>
  </footer>
  
</div>
