Hi. You can try this code from our API tab:

const myCarousel = document.querySelector('#myCarousel')
const carousel = new mdb.Carousel(myCarousel)

Here is something similar but it should prevent from double initialization:

document.querySelectorAll('[data-mdb-ride="carousel"]').forEach((el) => {
    let instance = Carousel.getInstance(el);
    if (!instance) {
      instance = new Carousel(el);
    }
  });

For tolltip try something like this:

document.querySelectorAll('[data-mdb-toggle="tooltip"]').forEach((el) => {
    let instance = Tooltip.getInstance(el);
    if (!instance) {
      instance = new Tooltip(el);
    }
  });

For multi-carousel try this:

document.querySelectorAll('.multi-carousel').forEach((el) => {
  new MultiCarousel(el).init();
});

Make sure to run this JS code after your page has loaded.
