The upgraded editor doesn’t support Internet Explorer version 7 or version 8 in compatibility mode. If you are using these browsers, you will use the older editor.
Specify how large the editor box should be for a rich text field by configuring the “Number of lines displayed” property in the field’s setup.
When you view or print content, Salesforce preserves the formatted version of the HTML in rich text area fields.
Searches of content that contains rich text area fields ignore images and tags.
Deleting a rich text area field moves it to the Deleted Fields section on the custom object or Salesforce Knowledge article types.
You can only convert rich text area fields into long text area fields. Any images are deleted the next time the long text area field is saved. After converting, markup is hidden in the long text area field but it is not removed from the record until you save the record. That way, the markup can be restored if you change your mind.
When a rich text area field is used in a formula, the HTML tags are stripped out before the formula is run.
Rich text area fields can be filtered and summarized in reports, but HTML tags and special formatting aren’t included in report results. For example, <b>some</b> <i>text</i> becomes “some text” instead of <b>some</b> <i>text</i> or sometext.
The text part of rich text area fields counts towards data storage for the object that contains the field.
You can copy and paste text from external sources such as Microsoft® Word, but you may have to reapply formatting.
You can use a rich text area field in a mail merge, but the HTML tags are included as text in the resulting document, and images aren’t merged.
Images in Rich Text Area Fields
The maximum size of an image that can be uploaded in a rich text area field is 1 MB. Only .gif, .jpg, and .png file types are supported.
