Repeater serve as a checkbox

I created my own calendar in the database, I added a month and day filter so that only the hours remained in the repeater. Now, I would like the customer to reserve more than one hour and send the order to another database.
I have no idea how can I make Repeater serve as a checkbox.
Can you help me with this?

This example uses a repeater to create a Multi-Select Dropdown .

The following examples use different input components (including checkbox) in Repeaters:

Input Components in Repeater
Use input components in a repeater, and apply inline and global actions to repeater content.

To-Do List
Let users create, filter, and update their own customized to-do list . The same functionality can be created using data binding or with the Wix Data API.
