The standard list screen
Most administration entries open the same kind of screen:
Search: type your text and click the magnifier icon; the Clean icon resets the search.
Add: click Add to open the entry form. Starred fields are mandatory; format errors are reported field by field ("The field ... is mandatory", "... must be numeric", "The date of the field ... is invalid").
Edit: click the edit icon on a line to open the same form pre-filled.
Delete: click the delete icon. Entries used elsewhere are protected — "You cannot delete this element" means bookings or records still reference it.
Print and Export: the left-menu tools print or export the displayed list.
Civilities
Administration, Others section, "Civilities management": the titles (Mr, Ms, Dr...) proposed on person forms.
Countries
"Countries management": the country list used in addresses and visitor records.
Cities
"Cities management": the city list, proposed with autocomplete on address fields.
Special days
"Particular days management": public holidays and special dates. Special days affect booking availability and recurring series — a weekly series skips or flags the holidays depending on your settings.
Good to know
The same pattern applies to dozens of other screens referenced across this guide: statuses, types, companies, departments, services, families...
Reference data is often shared across Hamilton applications; coordinate changes with the other administrators.
