Subcollections not displaying in ZotpressLib

Hello,
First of all, thank you for your plugin, it’s great ! I’m developing an Academic website and one of my pages is supposed to display a bibliography of all sources/articles/books that are used, based on a common Zotero Library, with various collections & subcollections

Using a dropdown Zotpress Library, I had several questions which I hoped you could answer:

1. Is it possible to display more than 10 results in the dropdown-style library (I know it’s possible in the searchbar-style, but I’d like it in the dropdown) ?

2. Is it possible to translate/modify the “Top Level Items”-notice ?

3. Finally, and most importantly, the dropdown menu shows all my collections and, when needed, the subcollections of said-collections. However, when I click on a collection, it won’t display my subcollections, only the raw content in it. For instance, I have a collection called “Legislation” with 2 subcollections and 68 items in total. When I click on it, all items show up, but that’s it. It doesn’t specifiy which items belong to which subcollection.

Thank you for your time !

Kind regards,
Vincent
