Findeo demo uses Contact form 7 plugin for contact form, and it’s recommended one. After installing this pugin go to Contact → Add new (or edit current one) and in Form field paste what’s below:
<fieldset> <div><label>Name</label>[text* your-name] </div> <div><label>Email<span>*</span></label>[email* your-email] </div> <div><label>Message<span>*</span>:</label>[textarea your-message] </div> </fieldset> [submit "Send"] <div class="clear"></div>
Than at the top of page you’ll see shortcode, for example (it will have different ID on your website):
[contact-form-7 id="123" title="Contact form 1"]
Use it on a page you want to have contact form.
