@diegoh it can only be done on the
add page and
edit page. For the add and the view page please use
FieldWidth in
Add/Edit page Field Properties, to set the field for each field and this would arrange your fields (E.g setting your first two fields,
FieldWidth to
col-md-6 makes the two fields share the same row and setting your first three fields,
FieldWidth to
col-md-4 makes the three fields appear on the same row). If you want to change the design for the view page, please edit the view page as a custom by clicking the custom checkbox beside the page name and you can then write your HTML code.
Note: phprad uses bootstrap, you can read more about bootstrap grid here (https://getbootstrap.com/docs/4.0/layout/grid/).
