Question Matrix Response Type

The Question Matrix response type allows users to create a group of questions that display in a matrix format, whereby each cell within the matrix represents a separate question. To use this response type, define the number of rows and columns you want in your matrix set and give each row and column a label or name. Each column can be a different question type. In the above screenshot, the first two columns are select-one questions, and the third column is a number question.

This response type only works when using Enketo, utilizing the Grid-theme layout. Forms are set to single page layout by default -- to change it, find the "layout" button in the formbuilder toolbar, select "grid-theme", save this change, and redeploy your form to make these changes live.

Enketo supports only up to 10 columns in versions less than 2.8.0, up to 13 including and after 2.8.0.

Create a Question Matrix in XLSForm

Alternatively, you can also build a Matrix Question in a XLSForm by following the instructions as outlined in the images below:

survey

type name label required kobo--matrix_list
begin_kobomatrix M1 Items assets
select_one yn Q1 Q1. Which assets do you have at home TRUE
integer Q2 Q2. Number of assets TRUE
end_kobomatrix

choices

list_name name label
assets car Car
assets bike Bike
assets tv TV
yn yes Yes
yn no No

settings

style
theme-grid no-text-transform

This method uses begin_kobomatrix, end_kobomatrix and kobo—matrix_list.

Following the steps above, you should see the question matrix shown in the screenshot below (In Enketo only):

It is also possible to include relevant and constraint conditions within the matrix as follows:

survey

type name label required kobo--matrix_list relevant constraint
begin_kobomatrix M1 Items assets
select_one yn Q1 Q1. Which assets do you have at home TRUE
integer Q2 Q2. Number of assets TRUE ${Q1} = 'yes' . > 2
end_kobomatrix
