Note that embedded forms will always create a new (lead) client when filled in. If you wish to have an existing client fill in a form, use the Send Form feature from the client view.
To embed a form, select the Embed widget and use this full embed code:
And use this:
<iframe src="PUT_FORM_LINK_HERE" frameborder=0 width="100%" height="500">
But replace the PUT_FORM_LINK_HERE with the url of the form you want to embed, e.g. <iframe src="https://app.edoula.biz/private/form/xyz123" ...
You can play with the height
value to avoid having a vertical scroll for longer forms.
