Marketo forms, by default, have set widths for many elements including all the form fields, labels and even the form itself. If you’re embedding your form in a responsive landing page, you might want to make the form fully responsive as well. With a bit of CSS, you can make your one-column and two-column Marketo forms look great on every device.

I was registering for a webinar this week and when I went to select my Country from the drop-down, I was greeted with a search feature for the drop-down. I immediately started Googling what JavaScript plugin they were using to see if I could use it on Marketo forms. It turns out, you can and not only is it super easy to implement, but it also makes long drop-down in your Marketo forms more user-friendly. I’ll walk you through how I did this in 4 easy steps.
