guideCKEditor integration

The code snippet below presents the integration of CKBox with a full-featured version of CKEditor using the CKEditor’s super build. This is a special type of the CKEditor build, which includes all the available plugins and features. Because of this, when using the super build, you will have to disable the CKEditor features which you do not want to use.

The sample below presents the result of the integration with the super build of CKEditor. Try pasting images from the clipboard directly into the editing area as well as dropping images — the files will be saved on the fly by CKBox.

You can use the toolbar button to open a CKBox window. Then you can manage your files or choose an asset that should be added to the edited content. The image embedded in the editor this way will produce a highly optimized <picture> tag. If the image has the description set in its properties in CKBox, the description will be automatically used as an alt attribute of the image embedded in the editor.

Below, you can find the code of the CKBox integration with the CKEditor super build presented above.
