How to customize the CKEditor menu toolbar in XWiki?
Navigate to the WYSIWYG Editor page using this path Administrator → Editing → WYSIWYG Editor or using the navigation shortcut and start typing "CKEditor" and select "AdminSection" page.
Before proceeding with any modifications or updates to your CKEditor advanced configuration, creating a backup of your current customization configuration is strongly advised if they exist.
Next, check the list of enabled/disabled plugins and toolbar features. Make sure to enable (uncheck) these plugins: colorbutton, font, justify. And also, enable these features: BulletedList, Copy, CopyFormatting, Cut, HorizontalRule, NumberedList, RemoveFormat, SpecialChar, Strike, Subscript, Superscript, Underline, Unlink, xwiki-macro
Finally, copy and paste the code below in the Advanced configuration section and save the changes.
// Note that this setting is composed by "toolbar_" added to the toolbar name, which in this case is called "Word".
// This second part of the setting name can be anything. You must use this name in the CKEDITOR.config.toolbar setting in order to instruct the editor which `toolbar_(name)` setting should be used.
config.toolbar_Word = [
{ name: "actions", items: ["Undo", "Redo", "Cut", "Copy", "CopyFormatting"] },
{ name: "styles", items: ["Format", "Font", "FontSize"] },
{ name: "colors", items: ["TextColor", "BGColor"] },
{
name: "basicstyles",
items: [
"Bold",
"Italic",
"Underline",
"Strike",
"Subscript",
"Superscript",
"-",
"RemoveFormat",
],
},
{ name: "paragraph", items: ["NumberedList", "BulletedList", "Blockquote"] },
"/",
{ name: "links", items: ["Link", "Unlink"] },
{
name: "insert",
items: ["Image", "Table", "HorizontalRule", "SpecialChar", "xwiki-macro"],
},
{ name: "document", items: ["Source"] },
{ name: "tools", items: ["Maximize"] },
];
// Load toolbar_Name where Name = Word.
config.toolbar = "Word";
Refresh your page, and you'll see a new menu toolbar.
