How can I make the Tabs vertical instead of horizontal?

Hello, here's a cloned copy of your form that shows the Form Tabs vertically https://form.jotform.com/62937945457977 (if you wish to clone this, here's how).

Now, since you never mentioned where you want it to be placed after setting it vertically, I just positioned it to the left (with a 10px distance from the edge of the form). Just change the margin values below if you need it to be moved further (e.g. say, you want it outside the form, set the margins as -20px -90px, here's how it will look like).

.tabs-list {

   width: 150px; /* this will make it shrink and force the content to be rendered vertically */

   position: absolute;

   margin: 0 10px; /* move it a bit to the left */

}

Place these CSS Codes on the Form Tabs widget's properties window like so:

Thank you!
