Form containers are the go-to element when you need the users of your web-app to send you information via the user interface. For example:

  • subscribe to a newsletter,
  • update their profile information, or
  • create a new entry in your database.

Add a form container

To add a form container in WeWeb, you have 5 options in the Add panel:

  1. the Form container in the Elements category
  2. the Subscribe form in the Elements category
  3. the Contact form in the Elements category
  4. the Form container in the Input & Controls category
  5. the Multi-step form in the Input & Controls category

Form containers

All 5 options follow the same logic. Which one you choose depends on your use case and personal preferrences. For example:

  • if you need a multi-step form, might as well start with the ready-made element instead of building one from scratch,
  • if you want a simple subscribe form, choosing that element will be faster than deleting inputs on the subscribe form.

Customize a form

You can customize the style of a form like you would any other element:

Style form containers

In the example above, we changed the width of the form and added shadows.

You can also add, remove, and customize elements inside the form container:

In the example above, we deleted a few elements, added a select input, and changed the direction of the div that contains the user inputs to display them horizontally.

Submit a form

To allow users to submit the form, you'll need to add a workflow.


For the form to be validated properly when the user submits it, the workflow should be on the Form container element itself, not on the button

Workflow on form container


Looking at the Navigator on the left in the example above, notice the lightning icon next to the Form container element. There's no such icon next to the Submit button element. This shows us we added the workflow on the correct element.

The form submission workflow should be triggered On submit. The actions that come after that will depend on your use case:

Workflow on submit

In the example above, when a user submits a signup form, we create their profile in the WeWeb auth plugin (action 1) before redirecting them to a login page (action 2).

UX best practices

There are a number of best practices related to forms that will greatly improve your web-apps accessibility and user experience, including but not limited to:

  • labels,
  • input states, and
  • what happens after a user submits a form (whether it's successful or not).

Labels on text inputs

In order to improve user experience, it's best practice to display a label above text inputs so that, when a user starts typing in the field, they have a reminder of what input they're on.

You have a couple of options to do that in WeWeb:

  1. you can add a static label above every input like we have in the form containers provided in the Add panel, or
  2. you can use enable the Advanced placeholder option in the Style tab of the input

Advanced placeholders on input fields

States on inputs

In order to improve your web-app's accessibility and user experience it's best practice to add states to form inputs.

After form submission

When a user submits a form, it is best practice to let them know if their form submission went well or not.

In terms of UX, you could do this in different ways. Most times, you'll choose one of 2 options:

  1. redirect the user to a success or error page, or
  2. display a success or error message on the current page.

To display a success or error message, you could use WeWeb's Alerts element or simply add and display a text element below the form to inform the user of the submission status.

Debugging a form

Features with user interactions like form submissions can be tricky to develop.

Here are a few things to look out for if your form is not working as expected.

The workflow is not working when you test it in the debugger

We recommend that you:

  • test each action of the workflow from top to bottom
  • when you see an error, try to understand what it means

Don't hesitate to open and search through the API response. Very often, APIs you're working with will send back a complex object with more information about the error inside:

The workflow is working in the debugger but not in preview mode

Check the following:

  • is the workflow on the Form container?
  • is it triggered On submit?
  • is the form button a Submit button? (check the Settings tab of the button)
  • is the form button enabled? (check it's not disabled in the Settings tab of the button)
  • is the submit button inside the form container?
