Creating forms can be done using the Form, FormSection and FormRow components.

Form is a top-level container which renders a native <form> element and provides utilities for displaying a title and description, as well as managing the space between FormSection.

FormSection helps in rendering sections of a form, which group together multiple form fields. It can optionally render a title and description.

FormRow manages the horizontal layout of individual fields.

All these components are implemented in terms of the lower level layout components (namely Stack and Columns) and can be freely mixed and matched to create complex layout as needed.

Let's see a basic example:

This form has a single section with two fields.


It's good practice use FormSection to group fields together - even in case of a single section - in order to achieve consistent layouts.

Let's add a title and description to the form:

Forms are generally quite useless without a way of submitting them. The Form component provides a way of rendering a standard submit button:

In case we need to, we can also add a secondary button next to the submit button:

Let's add a few more sections to the form, this time adding some titles and descriptions:

The form looks good, but in some cases we may want to customize the width of single fields. By default, FormRow makes all fields in a row of the same width, filling the available space.

This can be customized by wrapping a field in a Column component. For example, let's make the number take only 1/5 of the space, so that the street name has more room. Similarly, let's also make the city and the country narrower, to better convey the expected length of such fields:

This API may look familiar and it's not by coincidence. The FormRow component is a thin wrapper around the Columns layout component, which sets the default spacing between fields and the collapse behavior (try resizing the window and you'll see form rows automatically collapse on small screens).
