Resolve Editor Field Do Not Displaying in the NS CD Content Form

The possible reason why Editor Fields do not Display is when the preferred Content form is a custom form without the required functions. By default, Custom NS CD Content Form is the preferred form.

When customizing the form make sure to do the following:
1. Navigate to Customization > Lists, Records, & Fields > Record Types> NS CD Content> Forms tab
2. Edit the custom form set as preferred.
3. Click Custom Code tab then add these functions:

a. Page Init Function = pageInit
b. Field Changed Function = fieldChanged

4. Save the record.
