Settings > Online Bookings > Side Bars
To add a new side bar, type a title in the field marked "Side Bar Title". To edit a side bar, click "Edit" next to the side bar name.
Select which tabs you want the side bar to appear on and select the order (for example: selecting "1" from the drop-down will make that side bar the first in the list of side bars showing up on that tab). Note: the accommodations or rooms tab is the default tab on the booking engine, so you will most likely want the side bar to appear on this tab.
Select the bubble for either specials & packages/retail items OR custom HTML.
Select which specials/packages/retail items you want on this side bar OR type in a message or HTML.
