Is It possible remove the product from wishlist through wishlist button?

Hi,

If you customize the view displaying the add to wishlist button, you sure can do that. You'll have to set the qty parameter of the button to 0 and add a parameter add=0 to the URL. That will override the quantity in the cart instead of adding to it.
To know which view file you want to edit, you can activate the "Display view files" setting of the HikaShop configuration and then look at a page with that add to wishlist button. It will tell you which view file is used there and then you can edit it via the menu Display>Views in the backend of HikaShop.

Hi,

This would require some proper development if you wanted me to give you all the code you need to add.
I can only give some hints here.
In the view file which displays the add to wishlist button, you should find some code like this:

<a class="<?php echo $css_button . ' ' . $css_button_wishlist; ?>" rel="nofollow" href="<?php echo hikashop_completeLink($classical_url); ?>" onclick="if(window.hikashop.addToWishlist) { return window.hikashop.addToWishlist(this); }" data-addToWishlist="<?php echo $this->row->product_id; ?>" data-addTo-div="hikashop_product_form" data-addTo-class="add_in_progress"><span><?php
		if(!empty($this->row->product_addtowishlist_message))
			echo JText::_($this->row->product_addtowishlist_message);
		else
			echo JText::_('ADD_TO_WISHLIST');
	?></span></a>
