What is multi-select?

Comboboxes with the multi-select option allow selecting several values; each value is preceded by a checkbox.

Search masks only

Multi-select only works in search masks.

Enable the multi-select checkbox in the combobox properties.

Multi-select in the search mask.

The top entry plus the count of further selections is shown. On search the entries are combined with OR; the combobox no longer closes automatically.

Since a parameter can now hold several values, use IN/NOT IN in the SQL:

AUSDRUCK IN $param
AUSDRUCK NOT IN $param

instead of

AUSDRUCK = $param
AUSDRUCK <> $param

IN/NOT IN also works for single-value parameters.
