Form tabs aren't saving in the Sprout Forms plugin

Question

Strange bug: I'm creating tabs in a new form, but they're not saving. Goes like this:

1. Create a new tab
2. Re-name tab
3. Save form (to add / create a field)
4. Newly created tab is gone

Same thing happens whether it's my form or one of the default example ones ("basic" and "contact"). The "basic" form has two tabs; I checked the db to see if the tab data (names, number, etc.) is saved anywhere there but I can't see any table that contains it.

So maybe it's stored in a file somewhere? Which means maybe some kind of permissions issue? Much obliged for any guidance.

Answer 1

OK, heard from Barrel Strength / Sprout support. His reply:

Please create any fields that you need before adding the tab, then please go ahead and add the tab(s) then drag and drop the fields that you need into the new tab (rename the new tab in this step if you want) and finally save the form. The new tabs need to have at least one field to be saved with the form.

Since you can't create an empty tab, the trick is to create all your fields first -- or at least, one field per tab. Then, after you create the tabs, you can drag a single field to each tab and save the form. That will keep the tabs. After that, when you create a new field, you can select the tab it belongs to in the dropdown.

I think that's how it also works in the native Craft field manager? So hopefully this helps somebody even if you're not using Sprout Forms (which is awesome, by the way.)
