How to create multi selection grid with multiple inputs

Hi 

I have been trying to add a widget to collect availability of potential staff. Staff could be choosing the same time of day/week

I tried to use MultiSelect Grid but it keeps the selected of previous people which I don't want. even if I remove the writing option it comes up as booked

is there a widget I can add for this or can this be fixed?

Greetings and thank you for your message.

You are able to create a simple Input table with checkboxes. Please see my test form on the following link:

You can set the fields of the Input table to be Checkbox, which will allow users to select multiple options:
