Whatever CMS you use, Bootstrap Editor 2 can easily install there.
All popular CMS including Joomla, WordPress, Drupal 7 and many others already have CKEditor or TinyMCE installed as the default editor.
Correspondingly, to install Bootstrap Editor in these CMS you simply need to install the standard CKEditor or TinyMCE plugin.
Joomla uses TinyMCE as an editor. Therefore we need the TinyMCE plugin of Bootstrap Editor. Then, follow the standard TinyMCE plugin installation procedure.
If you want (or if your version of Joomla uses outdated JCE), you can install CKEditor as the main editor and then install the CKEditor plugin.
Please note that besides the CKEditor plugin for Joomla is not officially supported anymore (there are no updates, and Joomla 3 compatibility is broken), JS+ team has fixed and updated the CKEditor for Joomla module and distributes it for free. We also wrote detailed installation instructions.
Basically, it's similar to Joomla: TinyMCE is available by default, you only need to install the TinyMCE plugin.
Drupal 8 is a whole different story, because we ship a special Drupal 8 module for it. Essentially, this is the same plugin for CKEditor, but integrated with the Drupal 8 control panel.
CKEditor itself is already installed to Drupal 8 making installation simpler for this CMS.
Because Drupal 7 is still extremely popular we continue supporting it.
CKEditor is not installed in it by default, so you will need to install the Drupal 7 module, and then install Bootstrap Editor for CKEditor.
Here is an example of how to install the CKEditor plugin to Drupal 7.
Bootstrap Editor 2 can be installed to any CMS or a website based on any framework (RoR, Django or even your own). The simplest option is to built CKEditor or TinyMCE into your website, then the task comes down to just installing the corresponding plugin.
