RE: The list pages in the phone layout does not require details to be show
If you want to display less number of fields(1,Andrew,xxx) on a list i.e if you want to customize the fields shown in a list page ,You can use the property "fieldgroups" in the particular table of the list.
learn.microsoft.com/.../devenv-field-groups
fieldgroups
{
fieldgroup(Brick; "Customer Code", "Document Number", "Customer Name", Address, "Phone Number", photo)
{
}// DISPLAY FORMAT IN LIST
--There can be any number of fields inside fieldgroup based on your requirement.
Hope this helps.
