How to get startet with JamRoom?
Using Jamroom
After you've created a form field, there is a "Modify" button to the right of it, click that and you can change the settings for that field.
The search form is created using the jrSearch_form function, checkout your header.tpl or your header_menu_desktop.tpl and you'll see where its being used. You could probably add this code where you would like the search form to go.
{jrSearch_form class="form_text" value="Search Site" style="width:70%"}
Hope this helps,
