Dropdown independent

@richardb
It perfectly works! Thank you so much.

I have indeed another question. My dataset (VideoAll) has 14 items. I have 12 per page meaning that I have 2 pages for this dataset with a pagination bar to navigate.
When I make a research with my dropdowns, I have the correct number of items on the first page. But I always have my pagination bar which gives me the possibility to move to page 2 and see item #13 and item #14. How can I address this ? I hope I am clear.
Thank you
