Thanks for reply,
Unfortunately website on my local server currently.
I switched template to joomla standard(beez3) but add to cart and wishlist buttons still on two different rows.
I opened my website in inspection mode in Firefox browser and I saw add to cart and add to wishlist in 2 different divs(see ins1.jpg)
I cut code from add to wishlist div and paste it to div class=hikashop_product_stock before add to card button code
<a rel="nofollow" class="hikashop_cart_button" href="#" onclick="var field=document.getElementById('hikashop_product_quantity_field_1');if(hikashopCheckChangeForm('item',0)){ return hikashopModifyQuantity('1',field,1,0,'wishlist',126); } else { return false; }"><img src="http://lavochka/images/lavochka/icons/wishlist.png" style="float:rightstyle=padding-bottom:-40px" align="middle"></a>
And I have got 2 buttons on one line (see ins2.jpg)
One more comment, if I turn on the quantity option on the product, I see the quantity field on the place where I want to place add to wishlist button. I thought it might be helpful...
As you see, you was right on item 3. When I switched template to joomla standard (beez3) - I have got the compare button.
