Some products may only be sold on certain days and times eg Sunday lunch.
If you want to restrict the day / time a product is visible on the online menu, you need to edit the timeslots for a web category.
Login to https://www.touchoffice.net
Select the Products menu and click red PLU number to edit a product
Click Webshop Options tab and click Edit button to the right of the web category dropdown
Click the pencil icon for the required web category - the edit web category pop up window will now appear.
By default there are no start or end times set, so products in the category will always be visible.
Enter a start time and an end time for a specific day, that you want the products to be visible.
If you need more than one set of times then click on Add Time Slot and repeat the process.
The hiding of products is done at a web category level, so all products in the category will be hidden.
If you want to hide products so that they are not visible all day, set start / end times of 03:00 - 03:01 or similar.
