Form builder

Hi all,

We are looking for a form builder we can embed in our website.

Events use our website to manage vendors.  Vendors need to fill out a customer form created by the event in order to be considered for the event.

We hope to incorporate a form builder, drag/drop style that allows our event customers to create nice looking forms.  Then when a vendor applies they fill out the event form. The data (form view with filled in answers) needs to be viewable by the event.

We were using javascript from formBuilder.online and it was working reasonably well but he seems to have closed things down and we have some issues with it.

Can anyone recommend anything?  We are searching around but it is difficult because when you look for "form builder" you get all of the online versions.  We need something that runs from our server and hoping not to re-invent the wheel with this.

Thanks in advance.

Mark
