You can use some jQuery magic to do this:

```
$(function() {    $('#ddlSelectCinema').prop('disabled',true);    $('#ddlSelectSession').prop('disabled',true);});
```

This code will disable the "Select Cinema" and "Select Session" drop downs. Then you need an event handler on the drop downs:

```
$(function() {    $('#ddlSelectMovie').change(function() {        $('#ddlSelectCinema').prop('disabled', false);    });    $('#ddlSelectCinema').change(function() {        $('#ddlSelectSession').prop('disabled', false);    });});
```

This will not hide it, but it will disable them. You might want to also add a CSS class called 'disabled' or something and apply and remove that class as you disable/enable the. This way you can style the drop downs and make them look disabled.
