The core question should be updated. In advanced options, it should be possible to upload different pictures for the emoticons.

Emoticon from FontAwesome by default ?

ELse : we can already fix partially the html for JS to use boostrap class

ok, seems a good idea to do it asap

There are only one emoticon in FontAwesome .... :snif:

Denis, you are right. There is only one emoticon in FontAwsome. But there are a lot of other nice icons there. Could a smiley font be included in addition to FontAwsome?

We have 3 emote in FA.

In a not out plugin : i use image:

.. release and put the link here in some minute

Maybe better to use svg?
We can even adapt it for 10- or 7-point question then

SVG : yes .

Adapatation is not answers_html point : but do it if you want ;)

I already have a plugin for that :https://framagit.org/SondagePro-LimeSurvey-plugin/radioToStarRating (star only)

Just a registerScript

Fixed with commit a4f468cc

Sorry : i'm unclear .

I talk about the 2 slider_rating options : https://github.com/LimeSurvey/LimeSurvey/blob/master/application/helpers/questionHelper.php#L890

Stars + Slider with emoticon

Stars is done, not emoticon ;).

And : sure to be in 2.5X ? You think it's not a breaker API fix (template API) ?

Another issue: mandatory radio star show 4 stars only (1 to 4).

See included lss file + http://testing.sondages.pro/masterall/index.php/89495/newtest/Y

PS: maybe time to add a "reset" to emoticon slider too :)

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=20976

Emoji-slider: 11788

I will fix the emoji slider in a different branch
it is more complicated, though i may have to insert a new font
