This patch introduces an emoji picker int othe OPAC's tag entry form.
It relies on the emoji-picker library [1]
To test:
- Apply the patches
- Restart all services (just in case some caching is taking place):
$ restart_all
- Log into the OPAC
- Do a search, pick a record
- On the detail page for the record, click on 'Add tags'
=> SUCCESS: An input form is displayed, with an emoji picker on the
right.
=> SUCCESS: Choosing an emoji populates the input with it
- Set 'TagsModeration' and retry
=> SUCCESS: Proposed tags are displayed correctly on the staff interface
for tag moderation
- Sign off :-D
