Any Gravity Form multiple choice field (select, checkbox or radio) can be mapped to have the submission entries 
of another form as their values.
To create related fields edit a Gravity Form and go to ‘Related Fields’ from the Form Settings menu.

A plugin to dynamically populate Gravity Form fields with form submissions.

WebHolism

When activated this plugin allows Gravity Forms elements to be split into columns. To implement the columns three new elements (Row Start, Column Break, and Row End) which are introduced into the Gravity Forms administration area in a group labelled as Multiple Columns Fields.
For each form, in its form settings it is possible to enable and disable the plugin’s CSS and JS that are used by the plugin. The CSS file is responsible for the layout of the form, and the JS file is used to remove unwanted spacing generated if using conditional logic to hide form elements. It is advised to keep the CSS enabled at all times, but the JS should only be enabled in the case of hidden elements through the use of conditional logic.
** Note: Plugin no longer supports initial column specification using Sections in versions 2 and before. If updating plugin from a version prior to version 3, the form will need to be recreated with the current design definitions.**
Note: If updating from version 3.0.3 or earlier. If the columns are not displaying as expected, first please visit the Form Settings for each form and check the Enable CSS checkbox.

Multiple Columns for Gravity Forms

Gravity form is good but its lacking lots of functionality for layout creation. This plugin give multi column function to create within form. Doing exactly what it says. Just install and add columns. That's it. One suggestion though, if you can add css box to add css class to column, that will be great. 

Nice Plugin for simple functionality
