When collecting data, it’s common to ask respondents questions to which you already know the range of answers. At other times, it makes sense to provide a list of possible answers to prevent others from being offered. An example of this is when asking which participants attended an event when you have the event’s registration list beforehand; or when asking in which district/village the respondent lives in. It’s easy enough to create choice lists in SurveyCTO, but not as easy or recommended to build these lists when they have a significant size.
In our last webinar, we walked you through the SurveyCTO feature “pre-loading”, from which you can pre-populate forms with pre-existing data. We’ll continue guiding you on how to pre-load data; however, this time we’ll show you how to return a list of values instead of individual values, by pre-loading choice lists for select_one and select_multiple fields with pre-existing data.
Specifically, you’ll receive step-by-step guidance on the following:
- Attaching pre-loaded data to a form, to query from inside the form.
- The syntax of the search() function, which is used to query your attached pre-loaded data and turn into choice lists.
- Configuring the whole process of loading multiple choices from pre-loaded data using the online form designer.
By pre-loading choice lists, you’ll optimize your form’s performance and save time with form design.
