I've got the app working and all my entries entered. A few are causing a scroll bar to appear. I have reviewed the Timeline.js project docs and setting the height of the content area seems easy enough. However, after digging in on the 2sxc app wrapper, I am unable to find the right way to get that setting/option passed in to the timeline-embed object. Can someone point me in the right direction?
Answered my own question. Hopefully someone in the future benefits from this...
Very simple answer is to edit the height in the /TimelineJS/assets/styles.css
We missed this previously simply because it wasn't working - until we turned off CRM/Enable Composite Files and cleared cache, etc.
