How to merge and handle 2 symfony forms in one?
<p>I have 2 symfony forms:</p>

<p><code>SignupFormType</code> and <code>HouseRentFormType</code></p>

<p>Signup form look like: </p>

<pre><code>&lt;form ..&gt;
&lt;input name='email' .. /&gt;
&lt;input name='pass' .. /&gt;
..
&lt;/form&gt;
</code></pre>

<p>And the House rent form like this:</p>

<pre><code>&lt;form ..&gt;
&lt;input name='city' .. /&gt;
&lt;input name='price' .. /&gt;
&lt;/form ..&gt;
</code></pre>

<p>I want to combine them so they look like this:</p>

<pre><code>&lt;form ..&gt;
// house rent info:
&lt;input name='city' .. /&gt;
&lt;input name='price' .. /&gt;

//registration info:
&lt;input name='email' .. /&gt;
&lt;input name='pass' .. /&gt;
&lt;input type='submit' /&gt;
&lt;/form ..&gt;
</code></pre>

<p>And also to create a form type or smthng. 
Any tips on how to handle the submit?</p>

<p>p.s. I'm using symfony/form: ^3.0</p>
