The Store Form app provides blocks responsible for displaying a user form connected to Master Data through a JSON schema.

Before configuring the Store Form block in your theme, make sure you have already configured a JSON schema in Master Data. Otherwise, the customer form will not be saved appropriately. To learn more, please refer to Creating forms for your store users.

1. Add the store-form app to your theme dependencies in the manifest.json. For example:

   
   

   _10

   "dependencies": {

   _10

   "vtex.store-form": "0.x"

   _10

   }

   
   

Now, you can use all blocks exported by the store-form app. See the full list below:

Block name	Description
form	Top-level block, in which you will specify which entity and schema from Master Data will be used for building the form. It provides context to its 8 children blocks (listed below).
form-input.checkbox	Renders a checkbox field in the form.
form-input.dropdown	Renders a dropdown field in the form.
form-input.radiogroup	Renders a radio button field in the form.
form-input.textarea	Renders a big text field in the form.
form-input.text	Renders a small text field in the form with few available characters.
form-field-group	Renders different form blocks (such as form-input.radiogroup and form-input.text) based on the schema's sub-property type.
form-input.upload	Renders an Upload field in the form.
form-submit	Renders a button to submit the user form content.
form-success	Accepts an array of blocks rendered when the form is successfully submitted. Any children block is valid.

2. In any desired store template, such as the store.product, add the form block. In the example below, the form block is contained in a Flex Layout row:

   
   

   _13

   {

   _13

   "store.product": {

   _13

   "children": [

   _13

   "flex-layout.row#product-breadcrumb",

   _13

   "flex-layout.row#product-main"

   _13

   "flex-layout.row#form",

   _13

   "shelf.relatedProducts",

   _13

   "product-reviews",

   _13

   "product-questions-and-answers"

   _13

   ]

   _13

   },

   _13

   ...

   _13

   }

   
   

3. Then, declare the form block. Remember to specify which entity and schema from Master Data should be fetched to build the block.

If the form block does not have any children configured, a default form will be rendered automatically based on the JSON schema in Master Data. This reading and interpretation of JSON schemas is facilitated by the Reacht Hook Form JSON Schema library, which supports the Store Form blocks logic behind the scenes.

Prop name	Type	Description	Default value
entity	string	The entity in Master Data where the document will be saved.	undefined
schema	string	The JSON schema name will be used. The schema name is set in the API request to create it in Master Data.	undefined

4. If desired, complete the form block by adding and configuring an array of children blocks. You can use the blocks listed in the first table stated above. For example:

Prop name	Type	Description	Default value
pointer	string	JSON schema pointer, i.e., the JSON schema path (for example: #/properties/firstName) in which the form block inputs should be validated against.	undefined
label	string	Field name when rendered.	Property title

Prop name	Type	Description	Default value
placeholder	string	Placeholder for the text area input.	undefined

Prop name	Type	Description	Default Value
pointer	string	JSON schema path (e.g., #/properties/firstName) for validating form block inputs.	undefined
inputType	enum	Defines the type of the text field. Possible values are: input - renders a regular text field; hidden - renders a hidden text field used for pre-defining an editable value to be submitted to the form; password - renders a password text field.	input
value (optional)	string	Displays a pre-defined text to be submitted when the inputType is set as hidden.	undefined
label	string	Label of the input field.	Property's title
placeholder	string	Placeholder for the text input.	undefined

Prop name	Type	Description	Default value
pointer	string	JSON schema pointer, i.e., the JSON schema path (for example: #/properties/address) in which the form block inputs should be validated against. Note that since you are configuring a form-field-group block, the path must not include a schema sub-property, only a schema property.	undefined
uiSchema	object	Redefines how the form-field-groups block should render each sub-property declared in the JSON schema path defined in pointer. As previously mentioned, the form-field-groups already handle this functionality on their own. However, you have the option to override the sub-property types using a schema and redefine how each form block will be rendered.	undefined

Prop name	Type	Description	Default value
pointer	string	JSON schema pointer, i.e., the JSON schema path (for example: #/properties/address) in which the form block inputs should be validated against. Note that since you are configuring a form-field-group block, the path must not include a schema's sub-property, only a schema's property.	undefined
accept	string	By default, the upload input only supports image and PDF format files. If you want to customize it, you can use the format type you want by following this pattern: *.TYPEFILE. Learn more about the accept field.

• uiSchema object:

Where childName should be replaced for the desired sub-property name and the UIType should be replaced for one of the following values:

• default: Will consider the form-field-group own logic (e.g. using the React Hook Form JSON Schema library) for block rendering;
• radio: The sub-property will be rendered as a form-input.radiogroup block.
• select: The sub-property will be rendered as a form-input.dropdown block.
• input: The sub-property will be rendered as a form-input.text block with inputType set to input.
• hidden: The sub-property will be rendered as a form-input.text block with inputType set to hidden.
• password: The sub-property will be rendered as a form-input.text block with inputType set to password.
• textArea: The sub-property will be rendered as a form-input.textarea block.
• checkbox: The sub-property will be rendered as a form-input.checkbox block.
• upload: The sub-property will be rendered as a form-input.upload block.

The JSON schema created in Master Data is responsible for informing the form blocks about the data they should receive. It specifies the type of input expected for each form field from users.

When the user clicks the Submit button, the form blocks retrieve all input data and send it to the Schema validation. This process, which involves understanding the expected input and sending it to Master Data, is facilitated by the React Hook Form JSON schema library working behind the scenes.

If any unexpected answer is detected, and the form blocks does not match the Schema, Master Data will be unable to create a user form, and an error message will be returned to the user.

In order to apply CSS customizations to this and other blocks, follow the instructions in Using CSS handles for store customizations.
