###  Steps to reproduce

1. Go to Administrator Settings → Project → Project attributes

2. Go to the edit page of a project attribute


### What is the buggy behavior?

* The options "Required", "Visible", and "Searchable" are hard to understand


### What is the expected behavior?

* Begin of the insertion**For project attributes only:**End of the insertion Begin of the deletion Required:End of the deletion

* Rename label Begin of the insertion"Required" toEnd of the insertion Begin of the deletion to:End of the deletion "Required for all projects" Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Change hint text to: "Check to enable this attribute and make it required in all projects. It cannot be deactivated for individual projects." Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * This must only be changed for project Begin of the insertionattributes. 

* For the "Searchable" form field:

* Add hint text: "Check to make this attribute available as a filter in project lists."

* **For all otherEnd of the insertion Begin of the deletion attributes. OtherEnd of the deletion custom Begin of the insertionfields (including spent time, versions, users, groups)**

* KeepEnd of the insertion Begin of the deletion field types should keepEnd of the deletion the same Begin of the insertion"Required"End of the insertion label and description.

* Begin of the insertionKeep the existing description for the "Searchable" form field.

* End of the insertion The column header in the work package custom fields table Begin of the insertionshouldEnd of the insertion Begin of the deletion mustEnd of the deletion remain "Required".

* Begin of the insertion**For project attributes, custom fields and user custom fields:**End of the insertion Begin of the deletion Visible:End of the deletion

* Rename Begin of the insertion"Visible"End of the insertion label to: "Admin-only" Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Change hint text to: "Check to make this attribute only visible to administrators. Users without admin rights will not be able to view or edit it." Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * This must be changed for all custom fields: project attributes **and** user custom fields. This will fix ##56897. Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Flip the behaviour so that : Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * unchecked by default now Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * you check to limit the visibility to admins instead of current behaviour where you check to make it visible to non-admins Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion * Migrate so that the switch setting is flipped for all existing project settings Begin of the insertion


End of the insertion Begin of the deletion

* Searchable:

* Add hint text: "Check to make this attribute available as a filter in project lists."

* This must only be changed for project attributes. Other custom field types should keep the same label and description.


End of the deletion ### Context

These project attribute and custom field edit pages can be improved a LOT more than this (and also Primerised), but this is a smaller incremental difference to improve usability/comprehension.

**Note to QA:**

Apart from testing the new Project Attributes changes described above, some regression testing is also required. The regression testing involves the creation custom fields available through the `/custom_fields` path in the admin section. Currently available custom field types:

* Work packages

* Spent time

* Versions

* Users

* Groups


Also the respecting of the new `admin_only` flag for all the custom fields that have it on their creation forms.

The `admin_only` flag is applied only to the **Project Attributes** and to the **User custom fields** only.
