Using other jpList controls with Open Content Multi-item

Hi folks,
As always, thank you for a wonderful product!
I am interested in using controls offered by jpList other than the ones provided out-of-the-box with the Multi-item implementation of Open Content. For example, it appears that Open Content uses the Filter Toggle Bundle (https://jplist.com/bundles/filter-toggle-bundle), and let's say I would like to use the Checkbox Dropdown Control (https://jplist.com/controls/checkbox-dropdown), which is not included in that bundle.
I tried simply uploading the appropriate files to my template folder in DNN, then registering the files in the template using {{registerscript "jplist.checkbox-dropdown.min.js"}}, and adding the necessary HTML to the template, but the filtering did not work. What other changes do I need to make, or is this even possible?
Thanks,
Mick
