Modify EditForm.aspx and DispForm.aspx on Document/Image Library

[JWJ]

I've been tasked to make the current out of the box form view for editing or just viewing item properties more user friendly. I'm using SharePoint 2013 On-Prem. We have a content type that has 26 fields, out of the box it just one huge long list and we would like to modify this with Info Path like forms.

From what I can see online, I cant directly modify this form with info path because its not a list (Task list or regular list) which has this option in the ribbon. SharePoint designer no longer gives the preview of the site and ONLY shows the code. the problem I find with this code is that when i edit the EditForm.aspx and DispForm.aspx files in the library I don't see any reference to the columns, so i take a step back and look for reference to the content type, still don't see it.

So my question is how can I modify this form?

Hi Jeremy,

In attached you can find part of my HTML code, which I used with my list with ~70 questions.

That code helped me make the new and edit form look more friendly.

You can find there, how I refered to the columns in SP Designer.

Examples: 

• <xsl:value-of select="@Title"/>
• <SharePoint:FormField FieldName="Author" runat="server" ControlMode="Display" DisableInputFieldLabel="true" />
• <xsl:value-of select="@NewColumn1"/>

I hope it is something that you searched :)
