Slide show inside of Body Content
that's a hard point that i'm also dealing with.

Actually i imagine 2 differents ways to solve this :


i install the module paragraph
It is pretty anwsome by changing the way a user contribute. But it doesn't allow to add a slideshow in a Body field.
Creating a plugins for CKEditor that create (a new button) that will add the slideshow HTML in the Body Field.
This button will be like "Create a table" button, you will decide how many images is needed and you will just add the  to it.
The HTML is quite simple, for bxSlider (http://bxslider.com/) for Exemple you will need to add this :



&lt;div&gt;
  &lt;ul class="bxslider"&gt;
    &lt;li&gt;&lt;img src="/images/pic1.jpg" /&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="/images/pic2.jpg" /&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="/images/pic3.jpg" /&gt;&lt;/li&gt;
    &lt;li&gt;&lt;img src="/images/pic4.jpg" /&gt;&lt;/li&gt;
  &lt;/ul&gt;
&lt;/div&gt;



And for SlidesJS it's :

&lt;div id="slides"&gt;
  &lt;img src="http://placehold.it/940x528"&gt;
  &lt;img src="http://placehold.it/940x528"&gt;
  &lt;img src="http://placehold.it/940x528"&gt;
  &lt;img src="http://placehold.it/940x528"&gt;
  &lt;img src="http://placehold.it/940x528"&gt;
&lt;/div&gt;


I didn't start this plugins yet because i finally decide to use Paragraph but i think this plugins for CKEditor can be a good tool in the futur.
