All tables in concierge.com follow a similar format. The default view is always 10 items per page, and the gear icon on the top right will show you what columns you can view in that section.
In the below example, you can choose to also display "Type" and "Group" columns by clicking the "x". Just remember, the more columns you add, the wider the table becomes, so you may need to scroll to the right to view all data.
If you want to view/select more than 10 guests at a time, you can change the number of items per page by clicking that pull down menu. You can view (and select) up to 200 guests at a time.
Note: When completing a bulk action for guests, remember that you will need to do it for each page of guests. When you select all (by clicking the check mark to the left of the First Name), you are only selecting the guests on that page (in view).
