1st time building custom form and I'm experiencing overlapping input fields as well as a drop down box that doesn't show up.

Guys, first a little detail about my experience level (below amateur)…now that we’re clear there here’s whats going on. I decided to build my site using the wix platform because it had great reviews as for ease of use for beginners. So i’m building a site for my event/party rental business. Didn’t find the “bookings” app as a good fit to take rental reservations so I set my mind on building a custom for that would allow customers to submit a rental reservation request on the site. So I’ve built a database to collect the customer input, and I’ve somewhat designed the reservations page/form to my liking by adding and customizing the input fields. I’ve connected nearly all of the inputs to the fields on the database except the “drop down” (can’t figure out where i’m going wrong there.) After I hit preview to check my work immediately I noticed some fields are overlapping. I stopped and went back into the editor and tried adjusting the inputs but I can’t seem to figure out whats causing the overlapping. Secondly, I need help sorting out the drop down list. Lastly, I could use guidance on adding additional drop down options that would allow customer to pick the items they want to reserve/book and the quantities. I’ve watched numerous videos and read plenty of articles and nothing seems to pin point my issue. Please help. Below are screenshots of what I’m seeing…

This is the editor’s view…

This is what you see in the preview screen

Have you simply tried just logging out of Wix and logging back in to see if it just a glitch with your browser or the Editor that has caused things to appear to have moved, possibly clear your cache and cookies too.

Otherwise just click on the overlapping elements and move them so that they are not overlapping anymore and you can line up the elements so that they are equal with each other with regards to margins and placement.

As for dropdowns, you can do the dropdown list through either the settings itself or you can connect them to a dataset field that you can use for the dropdown list instead.
