Auto select all multiple choice questions

[Pedrovoliveira]

Hi, community!

I am facing the challenge of creating a "Select All" checkbox for a select_multiple question in Survey123 Connect. The question is to select the plots of a farm, and the options are dynamic, changing according to the farm. For example, if the farm has 15 plots, only those 15 options will be displayed. If another farm has 3 plots, only those 3 options will be shown, and so on.

Thanks!

Would cascading selects work for you:

The "Default" column in the XML form drives what multiselect values are automatically selected.  If you had two sublots called Farm 01 and Farm 02 you would input into the default column: Farm 01,Farm 02 and they will be selected by default.   If there's not too many sublots, you could try to just list every single one separated by a comma and see if that works.

It looks like the Default column is calculated when the survey is open, so it would be more challenging to write an expression that is dynamic off of the farm input from a prior question.
