I am really trying to get on board with the modern form designer. I have many active forms that I'd like to convert. Because I am using a lot of CSS and JS on the forms created in the classic designer, a lot of formatting goes away. Dragging the fields side-by-side is nice, because I can quickly correct those issues. Some others are not so easy, at least with the update we are currently on and which we will be staying with until we upgrade to 12 late next year.
I have the need to hide a submit button on an existing form (classic) and all JS I've tried fails for this particular situation. Here is a link to that post: https://answers.laserfiche.com/questions/225550/Hide-submit-on-form-if-hidden-field-is-blank--Classic-Designer#225552 Testing in the modern forms designer using rules works great, further encouraging me to convert my forms to the MFD. So, I converted this form, and now all the nicely sized fields I had set up are back to being the full width of the form. I know that with the modern designer you can still use CSS to customize the width of fields (so I could go in and do this for each one I want to be smaller ... uggh), but the classic to modern comparison documentation says that you can drag to resize the height or width of fields. I can't find a way to do this and it feels like a step backwards since the classic designer allowed small/medium/large/x-large options for quickly sizing the width of a field (and those options are gone). Is this drag to resize an option only in a version of Forms higher than 11.0.2307.40547? It seems that the convenient field masking is only available in versions of 11 higher than this so I have a feeling I'm facing the same with this situation as no matter where I place my mouse, dragging to resize width does not seem to happen.
