You mean for the end user or for an editor in edit mode?
Maybe you could use list property with just one Text field? Then there will be no custom development.
Depending what you need it for, categories might be a solution too...
Custom property is your other bet of course.
If you think that you might need more data than simple strings later it might be worth adding a separate content type for them.
Yes it is for the Admin user in the CMS.
I have a page in the CMS that requires either 1,2,3 or more textboxes but nothing is set in stone to the actual amount needed so I was wondering if there is a way that I could create my own Widget?
For example it starts off with one Textbox but if the user wants another textbox they could click ADD and a new textbox appears. The data could be stored in a List.
Any ideas if this is possible?
