On the drop down box if an item is booked currently it goes gray - would it be possible to change the color and in what file please?
On the attendees to a event we do not use the organization field in what file would we dig to remove the heading and field to not show on the page please?
Not sure about the grayed out part in the dropdown. It should be grayed out, yes, but to change that color... will have to check.
On the frontend attendees list, you control what fields are shown. In each field, there is a checkbox for you to designate if it is to be included in the attendee's list or not (version 2.7.x). Or are you talking about a different list??
