    Help sizing a matrix field

    Asked by Cattfoundation on June 14, 2016 at 10:07 AM

    Can someone please help me with this matrix. It works perfectly but looks crazy. How can I get it to fit properly on the form? The cells can be smaller. Also, is there a way to restrict each cell to one single character? Thank you!

    Reducing the text input width should shrink the matrix table width.

    Use this CSS code and inject it to your form.

    .form-matrix-values input {

        width: 24px !important;

    Regarding on the character limits, unfortunately, matrix table doesn't have that feature. However, you can add that limit when you use and customize your form source code http://www.jotform.com/help/104-How-to-Download-a-Source-Code-of-your-Form.
