I need to create a question of type matrix in which the user responds that the effort to pass from one scale to another (a application of the technical MDCA).
In the vertical must have a scale that, for example, from 1 to 5 and in horizontal have the same scale 1 to 5.
When the respondent is answering, he'll use the following criteria (always reading the line):
" - To exit the scale one and go to the scale 2 my effort is down. To exit the scale 1 and go straight to scale 3 my effort is medium. To exit the scale 1 and go to the scale 5 directly, my effort is extreme."
So I need of an array of multicolumn that would allow the use of dropdown menu, so that within each dropdown I could insert the standard level of effort that the respondent will have to use.
My second question is, how I leave the main diagonal "not selectable". In this example I showed, the effort to get out of range 1 and go to scale 1 is zero, so I like to keep the person to answer this diagonal ...
