+### Form example
+It is also possible to use the dialog for small forms.
+This can be used when asking for a password, a name or similar to have native form validation.
+
+To make the dialog a form the `is-form` prop needs to be set.
+When using the form variant you can also pass buttons with `nativeType` prop to add a native `submit` button.
+
+Note that this is not possible if the dialog contains a navigation!
+
+```vue
+<template>
+	<div>
+		<NcButton @click="showDialog = true">Show dialog</NcButton>
+		<NcDialog is-form
+			:buttons="buttons"
+			name="Choose a name"
+			v-model:open="showDialog"
+			@submit="currentName = newName"
+			@closing="newName = ''">
+			<NcTextField v-model="newName"
+				label="New name"
+				minlength="6"

+				required />
