Sorry for the late response, but didn't have a free minute till this time.
In order to rename the Online shop block please paste this URL string into as webadress yoursite.com/administrator/index2.php?option=com_modules&client=&task=editA&i d=35
and hit enter. Modifying the title input form you may rename this module. To edit the name of the Main menu please visit this URL yoursite.com/administrator/index2.php?option=com_modules&client=&task=editA&i d=3
In order to change the position of the left section you need to edit the style information of the div id="leftcol" html tag.
Please look for this part of the template css
Code:
#leftcol
{
float:left; width:190px;
}
and insert the
Code:
position:absolute;
left:10px
so it will be
Code:
#leftcol
{
float:left; width:190px;
position:absolute;
left:10px
}
Of course you may customize the position of the block editing the 10px value.
Please, let me know if you have further question.
Thanks
