Description

This method provides the ability to show a field in the editing form at any time. This can be useful for cases when you want to have extra form fields available, but only show them under certain conditions (for example when a particular value is selected, you might provide further options based on that value). Fields which will never be visible to the end user can use the hidden field type.

When a field is hidden, it is still part of the form and will be submitted with the other fields to the server, when the form is submitted, but it simply won't be visible to the user. The clear() method is used to completely remove fields if required.

This is the inverse of the field().hide() method.

Note that the show() method also provides the ability to show a specific field in the form display, and also extends that ability to being able to operate on multiple fields with a single call. For single fields, these two methods can often be used interchangeably. The key difference is in the return value - this method will return a DataTables.Editor.Field instance, while the show() method returns a DataTables.Editor instance. This can effect how you chain methods if you are using the returned value for chaining.
