How to disable or hide “Create New…” in dropdown input box?
In role permission manager, untick Create option for this document and for the role who shouldn’t see this
@rlarion1 I believe that you can do that using JavaScript…
frm.get_field('link_field').df.only_select = true;
// OR
frm.set_df_property('link_field', 'only_select', true);
