Material form templates
Use the left nav to filter the items
On this page you will find hundreds of form templates of all kinds. Filters in the side menu enable you to choose a preferred framework (Bootstrap, Bulma, Foundation, Material, Tailwind and UIKit). You can also select different types of forms and plugins.
Click on the "Toggle All" button to deselect everything and then choose the forms and plugins you want.
The forms open in a new tab. You can test them and see the PHP source code.
