Each section and question element has an automatically generated default label, which is defined by the position and level within the structure.
The default label representation is different depending on the level:

Level 1: capital letters - A, B, C etc.
Level 2: numeric - 1., 2., 3. etc.
Level 3: lowercase letters - a), b), c) etc.
Level 4: numeric - 1., 2., 3. etc.
Level 5: numeric - 1., 2., 3. etc.

The label can be customised in the detail panel of a section or question.

The default label of a specific section or question element can also be replaced by a custom text with a length of up to three characters.

Replacing the default label will not have any effect on the label of any other element, as the default label will always be generated based on the position and level in the structure.

It is possible to hide a label. This will take effect on Valuatic Touch and the Form PDFs.
