1) You’ll need to kind of set this one up manually, but something like the following would give you what you’re after:
<a href="#my-content" class="lightbox-selector" data-type="inline">Click Me</a>
So you’ll need to make sure to add a unique ID to the content you want to open up in the lightbox, then have a clickable link use that ID in the href attribute. You’ll also need to add a unique selector to the link via a class, which you’ll use with the [lightbox] shortcode.
2) You can try
Content Area Dropdown Element
Hope that helps
