No button on CKEditor in Drupal

[jrochate]

Hi.

I'm not in ckeditor API, but I found out that I need to add the following code in order to show the button on ckeditor cdn 4.7.3 under drupal module:

In plugin.js after this line:
init: function (editor) {
add
var lang = editor.lang.collapsibleItem; editor.ui.addButton('accordionList', { label: lang.buttonTitle, command: 'accordionList', icon: this.path + 'icons/accordionlist.png' });
sorry if this is not the way to do it, but here is the solution i found for my problem.

We need to UI buttton for plugin and need to update icon also icons: 'accordionList'

 editor.ui.addButton('accordionlist', {
            label: 'accordionlist',
            command: 'accordionList', // The command that was created by addCommand, above.
            toolbar: 'insert' // Defines the toolbar group. Can also specify an index for ordering: 'insert,30' or 'insert,100', or 'insert,0'.
        });

I am not sure if this is a best solution, but it solved my problem.
