Filed Style apply to form view

[MiY]

I would like a paperclip icon to be displayed in the request_item field of the sc_task table when a file is attached to the record set in the Request item.
To meet this requirement, I set the Filed Style as shown below.

However, while the icon appears in the list view, it does not appear on the form.

How can I apply this style to the form view?

Thank you in advance.

field style with value in it only apply for list and not on form.

for your case, you will require onLoad client script and then show that icon

For example: you can refer the OOTB client script on incident table which adds VIP icon

Field styles are not displayed in list view when the Value field is left empty

Thank you, so it's normal for it to only be applied to list views.
However, there are cases where it is applied to fields as well, as shown below.
Why is that? I haven't created a client script.

@MiY 

yes sometimes it shows and the behavior is inconsistent and is intermittent.

ServiceNow doesn't intend to fix this.

this KB talks about the same and you can create your own client script to show it always based on your logic.

Value-based field styles applied to forms inconsistently on UI14 and UI15
