List Fields Broken on Summary Criteria

Be forewarned: NetSuite's user interface is broken in list fields on the summary criteria tab of custom searches. It does not present a list of the options for the field. For example, in the standard criteria tab if you select the 'type' field, you get to select which types you want to filter. However, in the summary criteria tab, you do not see a list of choices.

There is a workaround which works, but is a bit ugly: create a summary criteria line for each multi-select choice for the list field. In each line, set the criteria to 'is' and type in the list option
