**As a** project portfolio manager
**I want to** have a comment field for project attributes
**so that I** better understand why a specific values has been chosen.

**Acceptance criteria:**

* [x] In the tab `Details` while creating or editing a project attribute, a new checkbox is available:
* **Add a comment text field:** Allows the user to add a comment related to the project attribute when selecting the value in the project overview.

* [ ] Once the checkbox is selected, when the user access the project attribute through the `Project Overview` a modal with the value to fill or edit will open and below it a text area will be available for the users to add comments.
* [x] In the `Project Overview` page, all project attributes are now editable individually, not by section.
* Begin of the insertion~~ThoseEnd of the insertion Begin of the deletion ThoseEnd of the deletion values that can be edited inline (e.g. short text, integer, float, list…) will be editable Begin of the insertioninline.~~End of the insertion Begin of the deletion inline.End of the deletion

* Begin of the insertion~~ThoseEnd of the insertion Begin of the deletion ThoseEnd of the deletion values that have comments or can't be edited inline will be edited in a modal (e.g. long Begin of the insertiontext).~~

* The comment field is added to the modal which opens when the user clicks to edit the field and is saved along with the value.End of the insertion Begin of the deletion text).End of the deletion

* [x] ~~The comment field is only shown for:~~ The comment field is shown for all field types.
* [x] ~~Boolean~~
* [x] ~~Date~~
* [x] ~~Float~~
* [x] ~~Int~~
* [ ] ~~Link~~
* [x] ~~List~~
* [ ] ~~Text~~
* [ ] ~~Long text~~
* [x] ~~User~~
* [x] ~~Version~~
* [x] ~~Calculated value~~
* [ ] Users that can edit a project attribute can also edit the comment.
* [ ] Users that can view a project attribute can also view the comment. The attribute modal should open, but in a read-only mode.
* [x] Changes to the comments are shown in the project activity
* This follows the same pattern as the project description column. A “Details” link is displayed, and the user can follow it to see a diff. Begin of the insertion

* If the comment functionality is disabled later on, when comments already exist, they are not displayed. Once the comment is reactivated on the field, all comments are shown again.End of the insertion

* [x] Comments can be selected as separate columns in the project list.
* The Begin of the insertioncolumn is named "X comment" where X is the name of the custom field the comment is configured for.

* TheEnd of the insertion text might be abbreviated. This follows the same pattern as the project description column. In case the text is abbreviated, a link to open a modal is displayed.

* [x] Comments can be exported (.csv, .xlsx, .pdf)
* [x] The comment field is a simple multi-row text field without text formatting, macros, tables, pictures etc. (we might change this to a “normal text field” later).
* [ ] The comments are displayed in the API and can also be updated using it.

**Permissions:**

* Administration of project attributes is limited to admins (same as before)

* Adding/Changing a comment on a project attribute requires the same permission as adding/changing the value of the associated project attribute.

* Viewing a comment on a project attribute requires the same permission as viewing the value of the associated project attribute.


**Technical notes:**

**Out of scope:**

* Attribute help texts fixed by the administrator are going to be reworked on this work package: <mention class="mention" data-id="65413" data-type="work_package" data-text="###65413">###65413</mention> Begin of the insertion

* Filtering and ordering on the comment in the project listEnd of the insertion
