Integrate hikashop layout in joomla menus

So, if I understand you, you want to have a listing of products on the left and a listing of categories. Like we have on our demo website, is that it ?
If so, you can create new hikashop content modules via the joomla module manager following this tutorial:
www.hikashop.com/en/support/documentatio...splay-front-end.html

By buttons what do you mean ? The bullet points ?
That can be changed with CSS. Most of the time, it's just about setting "_menu" in the module class suffix option of the module or in the UL class suffix option of the module.

Sure but I still don't know what you want to do. You didn't answer my question.
Could you give link of some screenshots to explain more what you want ?

Home is a joomla menu item. Inlogformulier is the title of your login module.
That's two different things and none of them are related to HikaShop. It's related to your template CSS. You need to edit the file creafeestje.nl/templates/beez5/css/beez5.css and change the CSS code there.
For example, to remove the bullet point, you need to remove the code:
ul.menu li a:link, ul.menu li a:visited {
color: #444;
background: url(../images/karo.gif) 5px 12px no-repeat;
}
and refresh your browser's cache to see the change.

The indentation is already set in your template CSS, so you need to remove CSS and not add CSS:

ul.menu {
list-style-type: none;
margin: 0 0 0px 0px;
padding: 0px 5px 20px 5px;
}

ul.menu li a:link, ul.menu li a:visited {
display: block;
padding: 7px 4px 7px 15px;
text-decoration: none;
}

This is not the place to ask for joomla template CSS styling. Please go on forum.joomla.org for that. I also recommend you to use firebug to style your CSS easily: www.tutorial9.net/tutorials/web-tutorial...opment-with-firebug/
