when i am trying to open a modal dialog in nintex form, neither SP.SOD.execute('sp.ui.dialog.js', 'SP.UI.ModalDialog.showModalDialog', options);
nor
SP.UI.ModalDialog.showModalDialog(options)
is going to work.
When I googled it, I found that it is because Nintex in O365 is a APP and form is displayed in iframe.

I often customize SharePoint Page Layouts and Views. It would be great if Nintex could also include the ability to customize List Views. Another idea would be custom queries of Lists with nice design options.

Option 1 - While working in the form editor it would be nice to include a button that opens the list settings in a new tab.

Option 2 - Open the list settings in a pop up dialog.

I find myself needing to close the current form that I'm working on to navigate to the list settings, make a change, and then go back to the list settings.

It would be amazing if we could include substring before and after as runtime functions in the forms designer.

At the moment you're limited to using the basic 'count' substring, which is very limiting. If we could specify the ability to substring before or after a character it would drastically increase the usefulness of forms for data manipulation!

It would be really useful (for large forms especially but even smaller ones too) if there was some sort of art board area in the forms designer that you could put objects on to move around rather than making the form itself really wide and then resizing at the end. This would be a dedicated workspace type area in the forms designer that persists.

Currently we can use the tab named "Controls in use" on the left side to view what controls we are using.
The problem is that when you are designing a form with many controls, we 'd like to filter that tab by ControlName or ControlType

Good day, i'm aware that this has been released on the responsive forms designer for the single line of text control. Many customers would like the same functionality to support other control types such as the multiple lines of text control. This will allow form designers to achieve some more advanced functionality when they are building their forms.

To select multiple elements in Nintex forms you must press Control + Click. On a Mac Control + Click is the shortcut to bring up the right click menu. When you select multiple elements on a form on a Mac (in the designer) a the right click menu pops up every time. This is very frustrating because it seems like you guys never tested the form designer on a Mac.

Is there a way to prevent that more than one person at a time modifies the same form, e.g. by a check-out/check-in functionality? It has happened more than once (due to misunderstandings or lack of communication) that two developers work on the same form - which results in the loss of the changes of one of them.

It would be great to have the "Render as Buttons"-option also available for the List Lookup Control (same functionality as for the Choice Control) [Classic Forms Designer]

This control should support the ability to save to a multiple lines of text column. Currently it is able to lookup text with the lookup() function from a multiple lines of text column. It ought to be able to save to such a column as well.

I would like to be able to check in/out forms while editing.
I also would like to support major and minor versions. where a save will generate a minor version you can be able to check with the designer role.

Need 3 level multi choice dropdowns in New responsive designer. Example

Level 1: [MultiSelection] Car,Bike,Bus etc.,
Level 2: [MultiSelection] Car-Steering, Car-Clutchrods, Bike-horn, Bike-Frontwheel etc.,
Level 3: [MultiSelection] Car-Steering-Lowcost, Car-Steering-Highcost,Bike-Frontwheel-18inch,Bike-Frontwheel-20 inch.

With the new responsive forms for SharePoint online - the paging option is great, but in many cases the initial request does not require the other pages until later on in the process. The requester is required to click through each page to get to the submit button. So rules to hide those other pages until required or the other option would be to have the ability to have a submit button to add to the 1st page.

The Nintex forms controls of Single Line Textbox, Multi Line Textbox, People, and Choice both allow for a Default value.

However, I do not see that option for a List Lookup control. It would be extremely helpful to be able to pre-select items in our list lookup.

Would like to have a control in Nintex Form get updated automatically when data type on the list column get modified.

For example :
Single text field modified to choice (dropdown list)

The expected result is to have the Nintex Form Designer automatically change the Single line text control into a dropdown list.

Bug: When objects overlap and you select one, the only way to move or resize it is to use the keyboard arrows to move it away from it's current position. If you select, then let go of mouse button, then click and drag it will drag the object on top (not the one you originally selected). Being able to change the order of overlapping objects would be good too (ie. bring forward, send back, as per Microsoft drawing tools).
