1. In the extended field, is there a difference between not using and using multiple lines?
A. The difference between the two is whether you can add a new line or not, and the maximum text length can alse be changed (as shown in the figure).


2. Can I write different things every time I select a square?
A. No. Whether it is "selection box" or "check box", you can customize the name and content, but once defined, you can't write different things each time, you have to go back to the Extended Attributes field to modify.

3. Is there a limit to the number of drop-down menus in the original basic field "Status"?
A. There is basically no limit, but it is recommended not to be too much.
