In SharePoint Online (Office 365), I have a very simple and basic custom list which consists of a few columns, and I would like to lightly customize this form. So, My questions are:
1) How can I add a separator line on a custom list's form? I wanna add a separator line on the form under certain field - How can I accomplish this on SharePoint Online using SharePoint Designer or JavaScript (Via ScriptEditor WP)? I am not allowed to use InfoPath nor any other third-party forms.
2) How can I add a sub-header/title on the middle of the custom list's form? I wanna add a sub-header/title on the form under certain field - How can I accomplish this on SharePoint Online using SharePoint Designer or JavaScript (Via ScriptEditor WP)? I am not allowed to use InfoPath nor any other third-party forms.
Example: As you can see in the example, I just wanna add a single separator line in between the fields, and 1 sub-header.
Could you please help me out?
