Is it possible to display the "Second Tree" dropdown menu in a Nextstrain group?

Hello!

Expanding on this discussion post in a broader context:

It is possible to add the (display) “Second Tree” dropdown menu for builds in nextstrain groups (both public and private)? This was brought up in nextstrain office hours today and @joverlee mentioned that this feature may not be available for groups yet. I had to leave the call so posting here for feedback and potential solutions!

Context

Within our Nextstrain group, we currently have seasonal influenza builds for h1n1, h3n2, and vic (B/Victoria) with all 8 segments with the following url structure:

Using the Displaying multiple tree’s url logic as defined in the auspice documentation, we can visualize tanglegrams beutifully with no issue.

However, the addition of the “Second Tree” dropdown menu would enhance the viewing experience for our users. My questions are:

  1. Is the “Second Tree” dropdown option available for Nextstrain Groups (both Private and Public)
  2. Is our current build URL structure correct for getAvailible API request Server API — Auspice documentation in the event that it is possible?

Thanks in advance!

Hi @eakin,

Thanks for bringing this up in the public discussion forum!

I did a bit of digging and found that the second tree dropdown is currently not available for Nextstrain Groups. I’m tracking this task in Add `secondTreeOptions` for GroupSource · Issue #1114 · nextstrain/nextstrain.org · GitHub, but I do not have a timeline for when this feature will be supported. I recommend continuing to construct the URLs for now.

Best,
Jover
