Hello There,
The input fields are not displaying because you are inserting a custom html code in a text element. Please use raw content element and insert your code:
<form action="https://www.getdrip.com/forms/189773227/submissions" method="post" data-drip-embedded-form="189773227">
<h3 data-drip-attribute="headline">Stay Inspired</h3>
<div data-drip-attribute="description"></div>
<div class="x-container">
<div class="x-column x-sm x-1-3">
<label for="drip-first-name">First Name</label><br />
<input type="text" id="drip-first-name" name="fields[first_name]" value="" />
</div>
<div class="x-column x-sm x-1-3">
<label for="drip-email">Email Address</label><br />
<input type="email" id="drip-email" name="fields[email]" value="" />
</div>
<div class="x-column x-sm x-1-3 last">
<input type="submit" value="Sign Me Up!" data-drip-attribute="sign-up-button" />
</div>
</div>
</form>
The code above is already formatted to display a three column row.
Hope this helps. Kindly let us know.
