Add tag UI

[thomaswilburn]

These should be surfaced, possibly based on a config value at the top of the document.

From our meeting:

Ways to collect photos, fact checks, exit poll posts, etc. Would we use this faceting more than users?
Amita: On debate nights, there’s more of a single bucket of content. But on a primary night, at least 3 or 4 different kinds of content coming in over the course of the day
Reporting from the field (voter comments, photos, various color)
Exit polls (is there an overlap between results and exit polls?)
Results
Written posts, not a static or dynamic graphic (no snapshots of the results)
Analysis (what does this mean, trends we see, etc.)
Tags by candidate?
Tags by media type? (photos, videos)
Tags by state?
We want the ability to set unique filters for each instance of the liveblog
Each post should be able to have multiple tags
The audience coming to the liveblog may want different things?
Allow users to filter/facet? Sort?
Recognize that users on mobile may not want to click through
A different layout for photo filters?
Be able to share a link to the filtered version (for social purposes)
Will we have enough volume of content to make this worth it?
Might be more useful on big primary nights, conventions, general election? But not smaller primary nights
Examples:
Sorting on NYT Cooking app
Books Concierge filtering
Is anyone doing this well in a liveblog context?
