wondering how to set the default value in the edit form? The solution is very simple,
Select the field in which you want to set the value, go to Advanced features, enter the value in the field Default value and save. The next time you want to add a new record, the value will already be filled in the edit form.
Yes, definitely. Simple javascript can be inserted directly into the field or for a more complex script you can use Scripting options, which you can find in the table settings.
