Replace Demo slider with my slider

My recollection is that you have to create your own new slider and give it a name.

I did that

well, I went back and found the slider info had disappeared from the images. So I re-entered that info for the fourth time and this time, it stuck.

I like it when things suddenly begin working.

How do you get a wow slider to show up in the drop down (where you can choose either Demo or no slider)? I have installed the wow plugin. Don’t know what to do from there. How do I put my slider on the Customizr?

You don’t need the wow slider: Customizr has its own. How-to here: https://www.themesandco.com/creating-a-slider-with-the-customizr-wordpress-theme/
