Angular PrimeNG ContextMenu Styling

Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. It provides a lot of templates, components, theme design, an extensive icon library, and much more. In this article, we are going to learn the Angular PrimeNG ContextMenu Styling.

The ContextMenu component displays a menu when right-clicking over any component. Many components provide a special integration with the ContextMenu component. The ContextMenu styling allows us to override the default styles by using the component style classes.

Angular PrimeNG ContextMenu Styling:

• p-contextmenu: It is the container element.
• p-menu-list: It is the list element.
• p-menuitem: It is the Menuitem element.
• p-menuitem-text: It is the label of a menuitem.
• p-menuitem-icon: It is the icon of a menuitem.
• p-submenu-icon: It is the arrow icon of a submenu.

Syntax:

:host ::ng-deep .p-contextmenu {
      ...
}
