Hello Charles. This single-item view is something I've wanted to do for
a long time but haven't had a chance.
I think method 1 is your best option.
Create a facet on item label which provides a way to select a single
item. Define a lens that shows an item the way that you like. Write
javascript "click" event handler that programmatically modifies the
facet selection based on the click. Then you can hide the facet itself,
as it won't be directly used for visualization.
The javascript *should* be simple but I'm not sure anyone has tried
using it this way. In list-facet.js there is a method called
setSelection that can be used to set or clear a selection on the facet.
You need to get hold of the facet object in order to invoke that method;
it will take care of updating the view as a result.

Hello,
(I'm working with Exhibit 3 Scripted.)
I have a special need for my work.
I need to build a web page that display only one item of my database.
This display follows the organization of a lense. The goal is to
display an "ID card like" web page describing an item.
My situation does not allow me to have only one JSON data file (I have
too many items). So I buils as many JSON file as items types.
My need is: from a "classical" Exhibit page who allow filtering and
other functionnalities, I want to be abble to point on one specific
item and go to a separate web page who display that item.
From this page it is possible to "navigate" from one item to another,
depending on the properties in the database. The lense use to displays
an item depend on the type of this last one.
I was thinking of two ways to implement this need but I'm not sure
this is possible. I need help to make my choice before to go ahead:
First way: Buildind a classical Exhibit web page then make a filter
(on the ID?) to display only one specific Item of my JSON file. The
link to the datafile is dynamically implemented depending on the type
of the item.
Second way: Building a specific Exhibit web page without facet and put
in the URL the data describing the selected item. Insert this data
_*in*_ the web page and use the Exhibit API to display the particular
item. In this way there is no direct link with an external JSON file.
I'm not sure where to put the data in the web page.
If I want to display the "ID card" of another item, I must search in
the ra JSON file, depending on the item type, and put again the data
through the URL.
I'm not really sure this two ways are performant and which one will be
the most simple to realize. Can you give me your feeling about this
two approaches?
Is someone had already implement this kind of need or knows another
solution to implement it?
Thanks in advance!
Best regards,
Charles
