How can I add time slots?

In a Application for sports training I want people to be able to choose one or multiple days. For each day they choose i want them to be able to to choose a time frame. This means a starting ann ending time for when they could come for tennis. 

Basically what it should look like ist this: 

Monday            From                 To             Priority

Tuesday           From                 To             Priority

Wednesday       From                 To             Priority

...

Maybe the solution could be to use Multiselect Grid widget, it will give you the option to add multiple days with multiple time frames that your users can choose from. And of course, they can choose multiple options as you requested. This is how it could look like:

And this is how it looks like after selecting few dates: 

That's of course if you want to have predefined time frames if you want them to choose random time you can take a look at Configurable list:

That way they can choose Day they want and time for that day, and by clicking a plus to add one or more days with a certain time.

There is also Appointment widget if that can work for you.

Hope it helps, if you need any additional assistance please let us know.

Thank you!
