How to load long list of timezones in BSS but keep HTML locked?

I want to load up this long list of timezone items in a dropdown picker

Normally this is just copied and pasted into the html, but if I unlock the html I lose bss drag and drop functionality.

Any suggested workarounds?

it turns out you can convert individual elements to html and not lose drag and drop functionality for everything else.

Yep, that's the beauty of BSS. Glad you worked it out and that's probably the easiest way to handle what you're trying to do anyways.
