    The option to preselect the radio button or checkbox inputs in the Matrix field

    Asked by alfsly on October 22, 2015 at 09:47 AM

    one of the features available for the radio box and check box tools is the ability to have answers automatically selected and ready to be deselected, so my question is, is there any way to accomplish the same effect when your matrix grid is set to radio / check boxes?

    thanks in advance, I can provide screenshots if it would help the point.

    Unfortunately, preselecting matrix options is not possible for now. You can only do this in the Radio Button or Checkbox field.

    I have forwarded this to our developers as a feature request. IF there are updates, you should know it in this thread.

    You can preselect the matrix fields using url variables.  This is easy to set up using the prepopulate.jotform.io app.
