I hide the unavailable slots by the following line you suggested: .time-disabled.time-disabled.time-disabled { display: none; } That works fine! My question is the following: If you click on a day which has no slots at all, you get the message that "choose another day" If one of my days are completely full it becomes red (that is OK). However, if someone clicks on that day he/she will see an empty line (because no more free slots are available). Is it possible to have the same message "Chose another day" here?
