selectall tag

The selectall tag is used with multiselect checkbox questions and tables so respondents can select a single option to trigger the selection of all other options.

1. Which of the following hotels have you stayed at in the past 12 months?
type: checkbox
instructions: Select all that apply.
selectall: 99
randomize: y
1. Hilton
2. Sheraton
3. Wyndham
4. Marriott
5. Hyatt
6. Best Western
7. Westin
99. All of these {anchor: y}

Details

• The selectall tag can specify a single option ID to select all other options (e.g., selectall: 99) or a subset of options by listing the select all option ID first, followed by the options that should be chosen with it in a comma separated list (e.g., selectall: 99,1,11,12).
• The selectall tag also allows for ranges of responses as input, similar to the series tag. For example, selectall: 99,1,2,3,4 can also be written as selectall: 99,1..4.
• Non-continuous sets are also allowed with selectall (e.g., selectall: 99,1,3..6,10,11).
• Multiple selectall tags can be added to a single widget.
• selectall can be paired with the exclusive tag or decorator to provide respondents with both "all of the above" and "none of these" responses.
• To fix the position of a select all option while randomizing other options, include the anchor: y decorator on the select all option as shown above.
