  • Date, Date-Time, or Date Range Picker
  • Color Picker
  • Visible Captcha (V2)
  • Submission Picker
  • Record Picker

  • Signature

You can embed complex forms that allow logged in users to update their profile. For example, a form that opens in a pop-up, to allow a logged in student to update their courses. Update forms The styling of your embed can be adjusted to match your brand in Softr.

​
Access logged-in Softr users in Fillavo

For custom code blocks, use the following code snippet:
Right below the line to Paste your embed code here, you can paste in the embed code you copied from Fillavo’s Share page for your form. That’s it!
Make sure to remove the first line in the code block, when pasting in your embed snippet (we’ve moved it over to later in the snippet, above).
You may also prefer using a simple custom embedding method as opposed to our built-in embedding snippets. Here’s an example snippet for passing in the email, full name, and record ID of the user that is logged in, using a custom iframe embedding method (if you need more customization):
In this snippet, replace the XXXXX with the unique ending of your form URL that you can find in the Share tab of your form.

​
Access the URL parameters/hidden fields in Fillavo

You can access the email, name, and ID URL parameters much like any other URL parameters in Fillavo if using the above methods to pass those in from Softr. Click here for more information.
Your URL parameters aren’t required to be called email, name, nor ID. You can rename these in Fillavo when registered, but the snippets above will need to be adjusted to replace the names with your desired names.
Fillavo forms also automatically inherit URL parameters from your Softr pages. If you have any page that has a recordID URL parameter, as long as you have that registered as a URL parameter in your Fillavo form, it will automatically get passed in!
