Rich Text Editor Configuration
Configuration
In this article you can learn about the various ways you can configure the RTE.
Toolbar
You have full control over which options should be available on the RTE.
In the examble above, all 34 options have been enabled. The options include copy/paste buttons, font styles like bold and italics, bullet lists and options to embed videos and insert images.
Stylesheets
It is possible to define specific styles that can be used when editing content using the RTE. You can use as many of these styles with the RTE as you want.
The RTE styles are defined in CSS files which can be created in the Settings section. Read the RTE Styles article to learn more about this feature.
Dimensions
Define height and width of the editor displayed in the content section.
Maximum size for inserted images
Define the maximum size for images added through the Rich Text Editor.
If inserted images are larger than the dimensions defined here, the images will be resized automatically.
Mode
The Rich Text Editor comes in two different modes: Classic and Inline.
Classic
The default mode which displays the toolbar at the top.
Inline
In this mode the toolbar is hidden, and only shows up when content in the editor is highlighted.
Blocks
Blocks can be added as elements in the Rich Text Editor. Configuration and rendering of Blocks is described in the Blocks in Rich Text Editor article.
Overlay Size
Select the width of the link picker overlay. The overlay size comes in three sizes: Small, Medium, and Large.
Hide Label
When this option is checked the label and description for the RTE property will be hidden.
Ignore User Start Nodes
Some of the backoffice users might be restricted to a specific part of the content tree. When the "Ignore User Start Nodes" is checked, the users can pick any piece of content from the content tree, when adding internal links through the RTE.
Image Upload Folder
Images added through the RTE is by default added to the root of the Media library.
Sometimes you might want to add the images to a specific folder. This folder can be configured using the "Image Upload Folder" setting.
Advanced Configuration
The RTE can also accept advanced configuration through the appSettings.json file fed into the TinyMCE configuration. This is within Umbraco:CMS:RichTextEditor and allows you to configure the following:
CustomConfig is slightly different from the rest as it extends the core config passed into TinyMCE.
Read more about the advanced configuration and how to set it up in Umbraco in the Rich Text Editor Settings article.
Allowing script tags in the RTE
Sometimes you want to allow your content editors to be able to add <script> tags into the RTE. This tag is classed as invalid by default which means the configuration needs to be updated to allow it. This is not something that can be done through the CMS and requires advanced configuration in the appSettings.json file. It uses the ValidElements property to append ,script[*] to the pre-existing list of valid elements as shown below.
