Navigators and Indicators in Angular Carousel component

03 Oct 2022 / 8 minutes to read

The navigators and indicators are used to transition the slides manually.

Show or hide previous and next button

In navigators, the previous and next slide transition buttons are used to perform slide transitions manually. You can show/hide the navigators using the buttonsVisibility property. The possible property values are as follows:

  • Hidden – the navigator’s buttons are not visible.
  • Visible – the navigator’s buttons are visible.
  • VisibleOnHover – the navigator’s buttons are visible only when hovering over the carousel.

The following example depicts the code to show/hide the navigators in the carousel.

Play button

Show or hide the play button

In the carousel, autoPlay actions have been controlled by using the showPlayButton property in the user interface. When you enable this property, the slide transitions are controlled using this play and pause button. This property depends on the buttonsVisibility property. The following example depicts the code to show the play button in the carousel.
