Ok, I figured this out - finally!!
Here's a whole bunch of information that I really think would be great if your Toolset team put into the documentation so that future people don't need to search around and find it here, but can find it where it's supposed to be:
THERE ARE 2 SPINNERS:
• The Filter Spinner is engaged when a user clicks on any filtered search (eg: Search for a taxonomy, etc).
• The Pagination Spinner is engaged when a user clicks to another page.
--- THE FILTER SPINNER ---
To place a FILTER SPINNER into your view, obviously you need to be using filters, but then in the "Search and Pagination" section of your view, you need to add a shortcode such as:
[wpv-filter-spinner position="after" spinner="Insert http location of your gif here unless you are using a default image" class="filterspinner"] Insert any text your wish here or leave blank[/wpv-filter-spinner]
More information about this shortcode found here:
https://toolset.com/documentation/user-guides/views-shortcodes/#vf-214918
You can POSITION this Filter Spinner using CSS, the controls are:
.filterspinner
.filterspinner > img
For example, the following will make the screen go dark and center the spinner (code gotten mostly from another post):
.filterspinner {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
background: rgba(10,10,10,.5);
z-index: 200;
}
.filterspinner > img {
margin-left: auto;
margin-right: auto;
margin-top: 50%;
display:block;
}
The above makes sure the spinner is ABSOLUTE and above all other objects. So it doesn't bump everything down each time it's engaged. A simpler version I went with was to remove the background line and make my margin-top 80px (I wanted it a little down from the top)
--- THE PAGINATION SPINNER ---
To place a PAGINATION SPINNER into your view, obviously you need to be using pagination, but then in the "Pagination and Sliders Settings" section of your view, there is a section under ADVANCED to control the spinner. This section controls the pagination spinner only.
TRICK: The reason I wasn't seeing the spinner was that it was offscreen. The default is it centers vertically! So on a long page you can't see it (Kinda dumb). I also believe it's already absolutely positioned - So I added this code to bring it to the top, matching the distance the same as my Filter Spinner:
.wpv_slide_loading_img {top: 80px !important;}
Notice I has to add the !important. That was the trick I didn't see at first and once I added that in - it worked.
Adjust from there!
