How to create a hover-triggered tooltip with SatPopover?

Use the SatPopoverHoverDirective with SatPopoverAnchor, as shown in the Add-on behaviors section. For example, add [satPopoverHover]='delay' to the anchor element to enable hover with an optional delay, simplifying interactive popovers.

SatPopover vs Angular Material tooltip – which is better?

SatPopover offers more customization and control over positioning, focus, and animations, making it ideal for complex overlay needs. Angular Material tooltips are better for quick, styled tooltips within Material Design systems, with less configuration required.

How to style the backdrop of a SatPopover?

Set the backdropClass input on the sat-popover component to add custom CSS classes. For instance, allows you to style the backdrop via CSS, as mentioned in the Backdrop section of the README.

Does SatPopover support server-side rendering (SSR) with Angular Universal?

The README doesn't specify SSR support. Since it relies on Angular CDK and DOM interactions, it may have limitations in server environments. Check Angular CDK's documentation for SSR compatibility and test thoroughly in your setup.

How to prevent SatPopover from closing on ESC key press?

Set interactiveClose to false on the popover component. Then, manually handle overlayKeydown events if needed, as explained in the Interactive closing section, to customize closing behavior based on user interactions.

What's the difference between forceAlignment and lockAlignment?

forceAlignment ensures the popover always opens with the specified alignment, even if it falls outside the viewport. lockAlignment prevents the popover from changing its alignment after opening, useful for maintaining position during scrolls or viewport changes.

popover — Accessible Angular Popover Component

What is popover?

SatPopover is an Angular component library for creating popovers—transient UI elements that display content anchored to another element. It solves the need for customizable, accessible overlay components in Angular applications, providing fine-grained control over positioning, focus, and interactions. Built on the Angular CDK's overlay API, it ensures reliable rendering and alignment within the viewport.

Target Audience

Angular developers building applications that require tooltips, contextual menus, dialogs, or other overlay-based UI patterns. It's particularly useful for teams needing accessible, customizable popover behavior beyond basic tooltip libraries.

Value Proposition

Developers choose SatPopover for its comprehensive API, focus on accessibility features like focus trapping, and deep integration with Angular's ecosystem. Unlike simpler alternatives, it offers advanced controls for alignment, scrolling, animations, and user interactions while maintaining Angular best practices.

Popover component for Angular

Use Cases

Best For

Creating accessible tooltips with keyboard and focus management
Building custom dropdown menus or contextual action panels
Implementing non-modal dialogs or informational popups
Adding hover-triggered help text with configurable delay
Displaying complex UI components in overlays (e.g., contact details, forms)
Angular projects requiring Material Design-like popover behavior without full Material library

Not Ideal For

Projects requiring pre-styled, drop-in popovers without custom CSS work
Applications prioritizing minimal bundle size and avoiding Angular CDK dependencies
Teams needing simple tooltip functionality without advanced positioning or focus management

Pros & Cons

Pros

Fine-Grained Positioning Control

Offers extensive alignment options with horizontalAlign, verticalAlign, and fallback behaviors like forceAlignment and lockAlignment, as detailed in the Alignment section of the README.

Robust Focus Management

Automatically traps focus within popovers and provides configurable autoFocus, restoreFocus, and cdkFocusInitial settings, ensuring accessibility compliance, as explained in the Focus behavior section.

Comprehensive Interaction API

Includes methods for programmatic control (open, close, toggle) and events for user interactions (backdropClicked, overlayKeydown), giving developers full control over popover behavior, as listed in the Opening and closing tables.

Customizable Animations

Allows adjustment of open/close transitions, timing, and scale values through inputs like openTransition and startAtScale, enabling tailored visual effects, as described in the Animations section.

Cons

No Built-In Styling

The component only handles transform origin; developers must implement all CSS for popover content, including backgrounds and shadows, as explicitly stated in the Styles section of the README.

Angular CDK Dependency

Requires @angular/cdk as a peer dependency, increasing bundle size and adding setup complexity for projects not already using the CDK, as noted in the Installation instructions.

Setup Overhead for Animations

Must correctly configure Angular animations providers (e.g., provideAnimations or provideNoopAnimations), which can be error-prone and adds initial development time, as highlighted in the Installation code example.
