With the help of Virto List Form Extender you can divide all fields in the list among different tabs.
Note: it is not mandatory to select a tab. You can leave tab field empty. In this case all field will be gathered on a single page.
First of all you need to add tabs you are going to use to the list settings.
Go to Virto Form Extender Settings of a required list and find “List of available tabs for selected list” block in the List Form Extender settings.
Use “Click here to add new tab” button.

Fill out two fields: “Tab name” and “Tab Order”. Both fields are required. Click “Save”.

Add more tabs the same way.

Now when you go to any field settings, you will be able to select required tab where this field will be displayed.

If you select “None”, the field will be displayed on top.
Now if you go back the list and try to view it or edit or add new Items, you will see that this field is placed into the selected tab. You can create any amount of such tabs and group fields of your list.
