Dropdown pass behind swiperjs, z-index issue or tailwindcss issue? - html

Question

I'm trying to use SwiperJS but I have a problem with the z-index I think.
I have my menu going below the slider and I don't understand how this is happening.
I tried to put a z-index: 1000 on the menu and a z-index: 1 on the slider.
I tried to put a z-index: -1 on the slider and it works, but I lose the use of the navigation buttons...
Am I blind? I think so.

<!-- If we need navigation buttons -->

I would just like the menu to go in front of the slider.

Answer 1

Since your codes are complex, I will explain this with a simple example. I think the problem is that you haven't given the relative class to the field you want to stand out. If you are using z-index, you should also add the relative class. In the example below, you can see that if you remove the relative class from the title, the title will go to the back.If this is not enough, you should add that it is important to the classes. SwiperJS might be squashing your classes somehow.

Answer 2

I found the solution, I simply added the tailwind classes to the header : z-20 relative
