Currently if offers a "removeDialogFields" that allows to remove individual fields in the dialogs (versus removing whole tabs with removeDialogTabs, and "dialogFieldsDefaultValues" defines default values for dialog fields.

## Installation

### 1. Copying the files

Extract the contents of the zip in you plugins directory, so it ends up like this

    ckeditor\
    	...
    	images\
    	lang\
    	plugins\
    		...
    		confighelper\
    			plugin.js
    			docs\
    				install.html
    		...
    	skins\
    	themes\

### 2. Adding it to CKEditor

Now add the plugin in your config.js or custom js configuration file: `config.extraPlugins='confighelper';`

### 3. Configuration

#### config.removeDialogFields

This entry is a string, the fields are defined as dialogName + ":" + tab + ":" + field. Fields are joined with semicolons. In order to learn the name of the parameters you can use the "Developer Tools plugin", launch that sample and open the dialog that you want to customize. Now a little popup with appear showing the info about that field, for example:

    Element Information
    Dialog window name : image
    Tab name : info
    Element ID : txtBorder
    Element type : text

so in order to remove the class attribute for images the config is:

    config.removeDialogFields="image:info:txtBorder";

removing another field

    config.removeDialogFields="image:info:txtBorder;image:info:txtHSpace";

#### config.dialogFieldsDefaultValues

This setting uses directly a JSON object as the configuration value, first an object that has the dialog names as properties, each property is a new object with the name of the tabs and finally each property name maps to the field name and it's value is the default value to use for the field.

An example might be much better as I might have messed up something in the description:

    config.dialogFieldsDefaultValues =
    {
    	image:
    		{
    			advanced:
    				{
    					txtGenClass : 'myClass',
    					txtGenTitle : 'Image title'
    				}
    		}
    };

#### config.placeholder

This a text that will be shown when the editor is empty following the HTML5 placeholder attribute. When the user focus the editor, the content is cleared automatically.

The value can be set in the configuration or as an attribute of the replaced element

    config.placeholder = 'Type here...';

#### config.hideDialogFields

This entry uses the same sintax that the 'removeDialogFields' option. The difference is that some fields can't be removed easily as other parts of the dialog might not be ready and might try to always use it, generating a javascript error. In other cases the layout might be broken if the field is removed instead of hidden.
In those cases it's possible to hide the fields using this entry, and the preview in the image dialog is an example of such a field.

    config.hideDialogFields="image:info:htmlPreview";
