Hello,

I'm afraid it does not seem to be possible to update Appointment Slots widget automatically. When an item is returned, you need to update the widget manually.

We do apologize for any inconvenience, please let us know if you need further assistance.

We have scenario where we want to create a request form which students will
use to borrow lab equipment.
User will
select equipment > number of available quantity will appear > quantity
selected (this will minus the total no. of quantity such as 9/10) >
submit form.
...

Hello again,

The scenario you shared should be handled properly by Appointment Slots widget, which you seem to use already. But, unfortunately, when the item is returned, you need to add +1 to appropriate option manually.
