Contenttype fields (all contenttypes) library
This library shows all the contenttype fields for every contenttype. This is an action which should only be made available to Site Administrators.
Using the filters on the right and/or specifying a search term, you can find the contenttype field(s) you're looking for.
Besides giving an excellent overview of every contenttype field there is, this library offers you another neat feature: you can set a ctfp for multiple fields at once.
Assume you want to set a specific ctfp on the Author field for every contenttype within the Portal & Web pages contenttype group.
To do that, first filter the contenttype fields list by selecting Portal & Web pages within the Contenttype group filter.
Then use the search term Author or select Author within the Physical field filter.
When needed, change the number of results shown in the library, and then select all the Author fields and click the Add property button.
The add/edit contenttype field property action is opened in bulk mode (see screenshot below).
To indicate you are setting a ctfp in bulk mode, a list of contenttype fields for which the ctfp will be set is shown at the bottom of the screen.
