Select (Dropdown)

1. What does the component do?

It is used for the selection of one or more options from a pre-defined list.

2. When should the component be used?

  • When selecting from several options (single or multiple choice) in a list.
  • If a selection must be made where the entries mutually exclude one another and no default value is to be set (in contrast to the radio button element).
  • When selection options are to be grouped.

3. Rules

  • There must be at least two options available.
  • The element always has a label.
  • Optional selections include the text ‘(optional)’ behind the label. The text ‘(optional)’ can be abbreviated to ‘(opt.)’ in short fields.
  • A question mark in the circle – in addition to the label – can be used for detailed explanations. A tooltip opens when this question mark is clicked on.
  • The text in the select element is always single-line.
  • If an entry is longer than the available width of the element, the entry’s text is abbreviated with ‘…’.
  • A pre-selection is not permitted with a mandatory field.
  • If no selection has been made yet, the element text says “please select …”.
