CKEDITOR ALLOWEDCONTENT CODE

While the style is applied to a single element, a widget allows any markup. When clicking on this style, CKeditor tries to convert the element in focus.Ī widget is a more complete and advanced solution to this problem: In view of the need to offer a set of predefined formats, it is common to use CKeditor styles, which allow us to associate an HTML element and a class (or ID, or even inline CSS). The first impulse of a Drupalista might be to use a combination of fields + field groups and/or paragraphs, overlooking a solution that in many occasions is simpler and easier to maintain, just as solid and that provides great advantages for the end-user: CKeditor widgets.

In some websites, such as online media outlets, these pieces of code can grow in number until they become a full-fledged library of simple and reusable components: quotes, information boxes, call-to-action, etc. First of all, it does not have to be parsed, so some special characters which the string format will not accept, can be used as element or property names in the object format.Įlement and property names can also be specified in more variants - as objects (fastest) or arrays (less recommended - may be slower).It is quite common for publishers to want to be able to insert predefined HTML fragments (small components and even layouts) into their content. The object format has a few more features than the string format. However, in most cases it should be sufficient. The string format is a compact notation for Allowed Content Rules, but it does not offer all features available in the object format. If a disallowed content rule removed a property which is required by any allowed content rule, that rule will not validate the element.Once rejected by a disallowed content rule, an element or its properties cannot be accepted by an allowed content rule.Once validated, an element or its property cannot be invalidated by another allowed content rule.It is possible to accept an element, but reject all its properties which will then be removed.If there are no allowed content rules for an element, it is removed.

Another rule may cause the editor to accept further element properties. The first rule applied to the element validates it (it will not be removed) and that rule may accept some element properties. Initially the element being filtered is invalid and all its properties are rejected. Then allowed content rules are applied one by one to the element. Once an element or its property is rejected they cannot be brought back by allowed content rules. An element may be rejected as a whole (if the rule specifies only the element name) or its properties may be removed. # Rules Applicationįirst disallowed content rules are applied to the element. For example each of the rules may allow another set of element properties. Multiple rules may exist for one element and one element may be included in numerous element lists. Note: Instead of writing “attributes, styles, and classes”, “ properties” will be used as a shorthand. the classes that these elements may have.the styles that these elements may have,.the attributes that these elements may have,.

Plugin developers will also need to set allowedContent properties which tell the editor what kind of content a feature allows in automatic mode.Īllowed Content Rule usually consists of four main parts: When configuring CKEditor 4 you will be mostly interested in setting the allowedContent and disallowedContent options. # IntroductionĪllowed Content Rules define which HTML elements, attributes, styles, and classes are allowed. Since CKEditor 4.4 Allowed Content Rules are complemented by Disallowed Content Rules that let you blacklist specific elements. Advanced Content Filter was introduced in CKEditor 4.1.
