How to customize SharePoint list view page

[BDO-Ramesh]

I wanted help to customize this look for better presentation, the search option is required here with a clear button. it would be helpful if we can implement search and clear buttons for ease to use the page. and also is it possible to change the page design and present the view

Hi, If this is SharePoint Online or On-Prem you have to create your own page either using the designer or Custom solution. I think powerapps is used to customize the New, Edit and Display Form. Maybe you can also try the list view formatting samples for SharePoint Online.

Thanks for your support! Tried the SharePoint online formatting samples, unfortunately other view are not pleasing for Search option. is there any solution to deploy JS or Jquery script for better presentation view.

I do not have subscription to Powerapps, not sure free access can help or not.
