Angular Sidebar Component

Angular Sidebar is a powerful and customizable responsive navigation component for any type of vertical navigation. Sidebar comes with built-in support for branding, navigation, and more.

## Supported content Sidebar come with built-in support for a handful of sub-components. Choose from the following as needed: - `c-sidebar-header` for optional header. - `c-sidebar-brand` for your company, product, or project name. - `c-sidebar-nav` for a full-height and lightweight navigation (including support for dropdowns). - `c-sidebar-footer` for optional footer. - `c-sidebar-toggler` for use with our minimizer.

## Customizing ### CSS variables Angular sidebars use local CSS variables on `.sidebar` and `.sidebar-backdrop` for enhanced real-time customization. Values for the CSS variables are set via Sass.

  ```scss

Some additional CSS variables are also present on `.sidebar-backdrop`:

  ```css
  --cui-backdrop-zindex: #{$zindex-sidebar-backdrop};
  --cui-backdrop-bg: #{$sidebar-backdrop-bg};
  --cui-backdrop-opacity: #{$sidebar-backdrop-opacity};
  ```

  


  ```css
  --cui-mobile-breakpoint: #{$mobile-breakpoint};
  ```

#### How to use CSS variables

  ```ts
  const vars = {
    '--my-css-var': 10,
    '--my-another-css-var': "red"
  }
  ```

  ```html
  <div [ngStyle]="vars"></div>
  ```
