Fix items on top of each other?

Question

In my vis.js timeline some items get stack on top of each other so that I can't see the ones that's in the back. I have tried adding margin, but that just makes the other ones (that look good) get put further away from each other.

Is this a common problem and how do I fix it?

I have checked the docs, but can't find an answer. http://visjs.org/docs/timeline/

Answer 1

For anyone else having the same problem, this is what I found.

• If the item is range type, it needs to have an end value or else it won't stack.
• I had to apply a maxHeight to the timeline options and had to set scrollVertical to true .
