Hi Flynax team
The template looks good.

Placeholder attribute is only supported in IE 10 and higher.
Is not it quite useful to change this in the template?

<input name="f[price][from]" class="numeric" type="text" maxLength="15" placeholder="from">


from
<meta http-equiv="X-UA-Compatible" content="IE=9">
to
<meta http-equiv="X-UA-Compatible" content="IE=10" />

best regards
