Custom List Item details view

Hi MET_FL ,

you can do three things:
1)  Card Designer
Go to your list, switch it to gallery mode and save it as a new view. Then select "Format current view"

Now select "Card Designer" and try to order your columns  in a way that makes sense

Now your data is displayed more compact as cards


2)  View Formatting
If that is not enough or if you want to have something more visually appealing then you could use "View Formatting"
Go to your view and select "Format current view" and then advanced mode. Here you can enter a formatting json to completely restructure your view using HTML and CSS

Take a look at this sample
https://github.com/pnp/List-Formatting/tree/master/view-samples/product-catalog 

But you need some HTML and CSS Skills to use that.


3) Power App
Or you create a completely new PowerApp to handle your data
See this tutorial here:
https://learn.microsoft.com/en-us/power-apps/maker/canvas-apps/app-from-sharepoint 

This is advanced but gives you the opportunity to completely re-format the view and the forms of your SharePoint List.

Best Regards,

Sven
