What is the best way to have a team submit their roster in a list form. Player # and Name?

Hello usarscommittee,

I highly recommend using the Matrix or the Configurable List widget. I created a demo form that will show how these functions work. Here's the link: https://form.jotform.me/61617653238459

Matrix Table
You can find it under the Survey Fields. Here you can specify the columns and the rows.

In order to adjust the width of the columns, you need to apply custom CSS to it. Here's an example:

/* Player # */
.form-matrix-row-headers +.form-matrix-values .form-textbox {
width: 50px;
}

/* Player Name */
.form-matrix-row-headers +.form-matrix-values +.form-matrix-values .form-textbox{
width: 200px;
}

This is the user guide on how to insert custom CSS on the form. (https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes)

Configurable List Widget (http://widgets.jotform.com/widget/configurable_list)
This widget will allow you to have full control on the number of items you want to add. You can also remove an item if you want.

Here's the reference guide I've used: https://www.jotform.com/help/282-How-to-Set-Up-the-Configurable-List-Widget

I hope that helps. Cheers!
